- I stumbled on this thread having just get an Internet connection. I did
- mail you from Compuserve a week or 2 ago about problems I'm having with FAS
- and SCO 3.2.2.
-
- FAS 2.09 locks the machine up occasionally so I stopped using it. FAS 2.10
- desn't seem to lock the machine up but it does sometimes lock the port up
- and the process with it. Control signals DTR,DSR,RTS,CTS are all high and
- no amount of kill -9 or >> portname will free it. I never get this problem
- under FAS 2.09 or SCO's driver. The problem seems to occur when the port
- is transmitting data rather than receiving. A modem dialler is particularly
- badly hit by it.
