Q: How can I have ProComm 2.4.3 accept a phone number that is more than 14 characters long?

A: In ProComm you can assign up to 24 characters to the plus (+), minus (-), at (@), and pound (#) signs, which have been reserved as long- distance codes (LD codes). To assign a string of characters, such as a calling card number, to an LD code, press <Alt-D> to access the dialing directory and <R> to revise. Then type one of the four reserved characters and enter the string you want to assign to it, followed by <ENTER>. Press <Y> to save the code to disk.

You can use one or more LD codes in combination with an entry in the dialing directory. For example, typing +1 dials the string assigned to the LD code '+' and the first entry in the dialing directory. See page 40 of the on-disk manual for detailed instructions on LD codes. --Pattie Devlin, CRC

Q: I use Vi-Spy 10.0 on an IBM PC/compatible. I just bought a fancy accelerated video card and now when I run Vi-Spy on startup from my AUTOEXEC.BAT, my display goes crazy. I can't give up Vi-Spy and I don't want to give up my new video card. What can I do?

A: As it scans for viruses, Vi-Spy checks various parts of your computer's memory, including video memory. As you have noticed, some video cards cannot tolerate having their memory scanned. To prevent Vi- Spy from scanning the video memory and eliminate the difficulties you are experiencing, add the following switch to the VI-SPY line in your AUTOEXEC.BAT file: AUTOVS NUMBEROFDAYS=1 VI-SPY /Q/NVM

Adding this switch to the Vi-Spy line does not significantly increase the risk of a virus infection. By making this minor change you can have your cake and eat it too! --Caroline Ferguson, CRC

Q: I can access UMIS (or the Library) from my PC, but not PennInfo and Gopher. What am I doing wrong?

A: Many users access PennNet resources via PC scripts, which routinize both PennNet logon processes and desktop software startup. A typical menu might look like this: (1=WordPerfect, 2=Lotus, 3=UMIS, 4=E-mail, etc.). In many cases, these scripts return control to the menu after a logoff, so a user is effectively "trapped" in the menu, and cannot access other PennNet resources until the script is changed. If this is your problem, ask your local system administrator to modify your menu to include PennInfo and Gopher--as well as the annex prompt, which will enable you to use new PennNet resources as they become available. --Dan Updegrove, DCCS

Q: I'm interested in subscribing to a few LISTSERVs, but I'm afraid of being inundated with mail messages. I understand there's a way to avoid this problem. Please explain.

A: The new LISTSERV software (release 1.7f) allows you to receive postings in either "digest" or "index" format. Digests contain the full text of postings collected during the last day or week. The index format contains just the subject lines from these postings, which you can later download if they interest you. You must subscribe to the list before you can request digests or indexes. The commands are SET <listname> DIGEST or SET <listname> INDEX. Not all lists have converted to the new software. If you send the command INFO REFCARD to a LISTSERV host, you will get back a handy reference of all commands available on the version of the LISTSERV software supported by that host. For more information on LISTSERVs, search PennInfo using the keyword "listserv." --Judy Smith, ISC Communications Group

Q: I'm using Microsoft Word 5.1 to lay out a form. When I use underlined tabs to create lines, they don't always line up on the right. Am I missing a step?

A: No, you're not missing a step. You are underlining hidden characters in some lines but not in others. You need to turn on underlining immediately before you press the tab key and turn it off before you press the return key to advance to the next line. If you don't turn off underlining before you advance to the next line, the hidden carriage return at the end of the line will also be underlined, creating a slightly longer line. --Tom Gudmundsen, CRC

March 1993

Q: During a consultation at the CRC, I was asked if I had installed the Macintosh System 7 Tuneup, which fixed some of the "bugs" in System 7.0.x. I wasn't sure if the Tuneup was installed or not. Is there any way to check?

A: To check to see if the System 7 Tuneup has been installed on your Macintosh, select About this Macintosh from the Apple menu. The window that is displayed indicates which version of system software you are using and the amount of memory available. If the System 7 Tuneup has been installed, there will be a black dot after the system version number. If the black dot is not present, indicating that the Tuneup has not been installed, you can get a copy at the CRC. Provide a blank double-sided double-density diskette and show your Penn or HUP ID. --Caroline Ferguson, CRC

Q: How is PennNet connected to the Internet?

A: PennNet connects to the Internet via two mid-level networks of which Penn was a founding member: JVNCnet and PREPnet. Both of these networks maintain connections to the NSFnet backbone, which links over 30 mid-level, and numerous international, nets. JVNCnet was originally the network providing access to the NSF-funded John von Neumann Supercomputer Center in Princeton. Although NSF rescinded funding for the center, JVNCnet remains as an international Internet carrier under the auspices of Global Enterprise Services. PREPnet was chartered by the Commonwealth to provide low-cost Internet access within Pennsylvania, and Penn maintains a seat on its steering committee. The two memberships--and separate leased phone lines from the campus to center city Philadelphia at 1.5 megabits per second (T1)--ensure that Penn will have a reliable connection to the Internet if either network should experience an outage. --Dan Updegrove, DCCS

Q: When I use the Macintosh System 7 Find command to locate files on my hard drive, it always searches my entire hard drive. Can I narrow the search to a folder?

A: Yes you can. Before selecting the Find command from the File menu, open the folder you want to search. In the Find dialog box, type the name, or a portion of the name, of the file you're looking for. Click on the More Choices button. Use the pop-down menu next to Search to select the entry Inside <the name of the folder you opened>. The Find command will only search the items within that folder. --Kristin Nelson, CRC

Q: What is the relationship between PennInfo and Gopher?

A: PennInfo is the University's official online campus-wide information system (CWIS), containing over 3,000 documents contributed by 50 departments. PennInfo is based upon the TechInfo software developed by MIT, which enables each "provider" department to upload documents to a central server maintained by Data Communications and Computing Services (DCCS). Gopher is CWIS software developed at the University of Minnesota, which has been adopted by hundreds of institutions on the Internet. Gopher has also been enhanced to serve as a network navigator, with gateways to other tools such as Archie and WAIS.

Penn supports Gopher as an Internet navigation tool that can also access PennInfo documents via a gateway developed by DCCS. Several Penn departments also operate Gopher servers. For access to Gopher, type t gopher at the annex: prompt. For access to PennInfo, type t penninfo at annex:. A second gateway enables PennInfo users to access Gopher via the Worldwide command. Although their command syntaxes differ, the two systems are complementary. Both contain enough online documentation to be essentially self-teaching. For details, see Penn Printout, February 1993. --Dan Updegrove, DCCS

Q: How do you cancel an Elm message?

A: There are a few ways to do it. If you decide to cancel a new message while you are in the message header, leave the subject line blank and press the enter key. If you are replying to a message, use the delete key to erase the subject line that was automatically inserted by Elm and then press the enter key. Elm will display "No subject - Continue with message? (y/n) n." Press the enter key to cancel the message. If you are already typing the text of your message in the Pico editor, press <control-x> then type <f> for the "forget" option to cancel your message. --Sheila Fleming, CRC

February 1993

Q: When I've finished searching PennData or Franklin, how do I exit the system?

A: The Library recently modified its system to make it easier for users to exit. If you accessed PennData or Franklin through the Internet or from the PennNet annex: prompt, typing stop at any Franklin/PennData screen will return you to your network prompt. If you accessed the system from the PennNet DIAL: prompt, typing stop at any Franklin/PennData screen drops your connection completely. --Peggy Yetter, Van Pelt Library

Q: Are baud rate and bits per second equivalent measurements of modem speed?

A: A baud is the unit of a modem's signalling speed, or the number of changes per second in the state of the carrier tone. Early modems only indicated one bit (0 or 1) per change of state, so baud and bits per second were equivalent units. In order to send data faster, modem designers began to use one of several different signals per change, each representing a multibit combination. So although the signalling rate (baud) may not increase, the number of bits conveyed by that rate can be much higher. Because consumers have become familiar with the term baud, vendors and the trade press often continue to use the term inaccurately (that is, when they really mean bits per second). The important specification for a modem is the data transfer speed, measured in bits per second. Dividing this number by 10 yields an approximation of the number of characters transmitted per second. --Randall Couch, ISC Communications

Q: Since the current version of Vi-Spy doesn't produce an on-screen pinwheel to indicate that it is checking my floppy disks, how can I be sure Vi-Spy is loaded and working?

A: There's an alternate way to have Vi-Spy indicate that it is checking floppy disks. Vi-Spy no longer produces the familiar pinwheel because it can now check floppy disks from within applications, such as WordPerfect, and a visible indicator would "break through" the screen display of the application in which Vi-Spy is checking. Now you can have an audible indicator instead--a low-pitched "beep."

To add this setting you must modify your AUTO-EXEC.BAT file. Add the following setting to the Vi-Spy lines in your AUTOEXEC.BAT: RVS /SOUNDON (To turn off the "beep," modify the AUTOEXEC.BAT file in the following manner: RVS /SOUNDOFF) With the addition of this setting, you can reassure yourself that floppy disks are being checked for viruses. --Caroline Ferguson, CRC

Q: Last year around this time there was considerable talk and panic about the Michelangelo virus, which was to "go off" on March 6 and destroy the information on the hard drives of infected IBM PC/compatibles. I know that Vi-Spy can detect and remove this virus, but I wonder if I should be especially attentive during the coming months?

A: Good question. Any resurgence of the Michelangelo virus appears unlikely. It was one of the most hunted viruses ever, and the chances of it still being undetected on a floppy disk from which it could spread are low. You should not, however, believe that the problem of viruses has ended. New viruses are being written and released everyday. Continue to use antiviral software on your computer and make sure you keep it up to date. Note that version 11 of Vi-Spy is due for release around the time you read this. For Macintosh users, the current version of Disinfectant is 2.9. --Caroline Ferguson, CRC

Q: Is there a way to do a single search of a FileMaker Pro database that would return the records of people living in a specific set of ZIP Codes?

A: While viewing a layout which includes the ZIP Code field, select Find from the Select menu. Click on the Zip Code field in the layout and enter the first ZIP Code. Now go to the Edit menu and select New Request. Click again on the ZIP Code field and enter your next ZIP Code. Repeat the procedure for each additional ZIP Code. Only when you have finished entering ZIP Codes should you initiate the search by clicking the Find button. FileMaker Pro will return only the records of the people who live in the zones you specified. --Dan Dougherty, CRC

November 1992

Q: I recently received a network ID and password. When I try to log on to the network, I get a message saying that my password is invalid. I know I'm typing it in correctly. What's going on?

A: Check to see if Caps Lock is on--PennNet passwords are case sensitive. If turning Caps Lock off does not work, you may need to reswipe your PennCard and enter a new password. When you do, be sure to note the case of each character in the password.

You can reswipe your card at these PennNet Authentication stations: PENNcard Identification Center, Suite 323A, 3401 Walnut St.; CRC, Locust Walk at 38th St.; Engineering CETS, Room 164, Moore School Graduate Wing; Biomedical Library, Johnson Pavilion; Vance Hall, Room 212 (for Wharton users only). If your PENNcard does not validate, contact the PENNcard Identification Center. --Sheila Fleming, CRC

Q: I have used the StartUp Programs group in Microsoft Windows 3.1 to designate certain programs to start automatically when Windows loads. This saves me minutes every day, but sometimes I want to start Windows without loading these applications. Is there a way to do this?

A: Yes, there is a way to temporarily disable the StartUp Programs group. Press and hold down the Shift key when you start your Windows 3.1 session. When the Program Manager appears, release the Shift key. Windows 3.1 will have loaded, but not the applications in your StartUp Programs group. --Caroline Ferguson, CRC

Q: How do I get my e-mail address in the WHOIS directory?

A: The online directory of e-mail addresses at Penn is maintained by Data Communications and Computing Services (DCCS) and is currently limited to faculty and staff. The primary data source is the summer survey conducted by Telecommunications for the Telephone Directory. DCCS plans to add student names and addresses in January. To check your listing, enter whois at the DIAL: prompt or t whois at the annex: prompt. To correct your listing, send e-mail to directory@dccs with your name and department. --Daniel Updegrove, DCCS

Q: My DeskWriter printer recently started printing the error message "no DTR handshaking." What's the problem?

A: If you recently upgraded your Macintosh to System 7, that is the most likely source of the problem. To use the DeskWriter with System 7, you need to upgrade the DeskWriter drivers to version 2.2 (for a Macintosh with less than 4 Mbytes of RAM) or 3.1 (for a Macintosh with more than 4 Mbytes of RAM). Version 3.1 provides background printing to the DeskWriter. The updated DeskWriter drivers are available at the Computing Resource Center's Locust Walk facility (Monday-Friday, 9 AM- 4:30 PM). Bring your original DeskWriter disks and one blank disk for a version 2.2 update or two disks for a version 3.1 update.

If you are not running System 7, there may be a problem with the printer cable. You might try replacing the cable to correct the problem. --Kristin Nelson, CRC

Q: How do I change my default font in Microsoft Word 5.0?

A: Choose Preferences from the Tools menu. Click on the Default Font icon, which appears on the left side of the Tools dialog box. In the Default Font and Default Size boxes, select or type the font and point size you want to use for the current document and all new documents. Click the close box in the upper-left corner. --Sheila Fleming, CRC

Q: I use MS-DOS 5.0 and Windows 3.1. Which of the drivers and memory managers, such as HIMEM, SMARTDRV, and EMM386, should I be using--those that came with MS-DOS 5.0 or those that came with Windows 3.1?

A: You should be using the drivers that came with Windows 3.1. They are the newest versions of these drivers and can be used with MS-DOS 3.1 or later. (The CRC recommends that you use DOS 5.0, which provides the most stable environment in which to run Windows.) -Pattie Devlin, CRC
