- Three times within the last few months, my computer has `frozen-
- solid' after I have left my word-processor unattended. Having
- followed the discussion for the last week or two in this group, I
- am beginning to suspect that the problem may be that my modem is
- not hanging up correctly. I twigged to this possibility tonight
- when the phone rang while I was using the word-processor a half-
- hour after I had exited my communications program: I answered the
- call, and when - five minutes later - I tried typing at the
- keyboard, the computer was frozen.
-
- I am using Qmodem 4.31 and a Patriot 2400i 2400 baud internal
- modem. (I always exit from QMODEM using the Y option [drop DTR]
- and never the x option [leave DTR up].)
-
- What should I be looking for? Should I fetch a utility from,
- e.g. SIMTEL20, to display on-screen a mock set of modem LED
- lights (to be run after exiting QMODEM)? If so, what utility
- should I use and what light's being on would indicate that the
- modem has not disconnected properly? And if the modem has not
- disconnected properly, how do I force it to?
-
- Or, instead, after exiting QMODEM, should I run MicroSoft's
- diagnostic program MSD to report on the interrupt status, etc.?
- If so, again, what should I be looking for? And how should I
- correct it?
-
- Or, should I be doing something else? (I could of course do a
- cold reboot, but that's a bit drastic, especially since I use the
- modem a dozen or more times a day.)
-
- Please, any help would be most welcome. Thanks.
