My apologies is this has been discussed here before; the sheer volume of articles on this newsgroup prevents me from reading it more than sporadically. Anyhow: within the last few weeks I have been having a problem with my communications software: ProTerm version 2.1. At irritatingly regular frequencies when using ProTerm, my keyboard has either (a) locked up completely, and/or (b) spontaneously sent a large number of the same character to the mainframe to which I was connected, on one occasion deleting two lines of a file I was editing with Jove. Both of these conditions typically necessitate turning the power off and restarting; the keyboard freeze extends to the control-open apple-reset combination. Lately, I can count on at least one of these maladies striking my computer at least every half-hour; in fact, it happened twice while I was writing this very article (!). Actually, come to think of it, this problem is not entirely restricted to ProTerm; a few weeks ago when the problem was first manifesting itself, the keyboard froze when I was running SoundSmith. This was odd, because while the keyboard was completely frozen, the mouse, which runs through the keyboard, was functioning normally. Is this some kind of virus? If so, how can I get rid of it? Thanks for any help, Sean McAfee smcafee@jarthur.claremont.eduuuuuuuu

You might not have a good connection between your keyboard and your computer. At the next lockup, jiggle the cable between the keyboard and computer and see if that clears up the problem. ProTERM is very interrupt driven, and keyboard quirks really confuse it. (That and a remote system constantly sending ^Ms are two common causes of ProTERM lockups. The second I am only able to fix by inducing line noise and then trying to interrupt the process, or dropping carrier.) Also, I suggest you get ProTERM v2.2. V2.1 has problems, including but not limited to Kermit protocol and VT-100 emulation. V2.2 has less problems. >Actually, come to think of it, this problem is not entirely restricted to >ProTerm; a few weeks ago when the problem was first manifesting itself, the >keyboard froze when I was running SoundSmith.

Viruses are more likely to destroy data or print cute messages on the screen, not randomly lockup keyboards. More likely it is a hardware problem. >Thanks for any help, >Sean McAfee >smcafee@jarthur.claremont.eduuuuuuuu -- /// ____ \\\ "It says, `Golgafrincham Ark Fleet, Ship B, Hold 7, Telephone | |/ / \ \| | Sanitizer, Second Class,' and a serial number."

The problem in my case seems to be power fluctuations: the monitor will flicker for a second, and when it's over my keyboard has (a) locked up, (b) sent a random character or three, or (c) sending an endless string of whatever character I happened to be typing when the flicker hit. It happens most frequently using ProTERM, but has happened in AppleWorks and other programs. Sound familiar? Hope This Helps(TM), --rubio (rubio@uiuc.edu)

These problems also remind me of what happened when I accidentally dumped water on my //c's keyboard. Luckily, opening it up and blowing a hair dryer on it cured the problem that day, and I haven't had any problems with it since.

From what I understand, I need to buy a new cable, keyboard, or both. But, I've found that by jamming a pen or pencil in between the side of the keyboard and where the cable plugs in that it stops the problem, at least temporarily. Of course, I don't necessarily recommend you try that. It might just make a bad situation worse. ---- Internet: bill@pro-gateway.cts.com
