Pardon me if this has already been discussed, but lately I am
having a puzzling problem.
Hardware: 286 pc, USR 2400 modem
Software: SCO 2.2.1, news, mail, etc.
Problem:
Whenever a system dials in to transfer mail/news, frequently
the getty that is respawned after that system disconnects is
not associated with the outside world. A kill -9 has no effect
at all. Disable/Enable doesn't help. ps still shows a getty
running, however where there is usually a "?" in the tty column,
there is now "tty2E" (the modem line).
Any attempt to dial-out gets a "line in use" error or worse,
just plain hung.
Does anyone know what's going on? Is there a fix for this?
All help appreciated...

A kill -9 has no effect ^^^^^^^^^^^^^^^^^^^^^ [rest deleted] Nearly all the time such a thing happens, it has something to do with hardware malfunction. In case of serial lines, it is often a problem of missing flow control to become active (ie the driver has seen XOFF and is waiting for XON or the corresponding hardware lines are not asserted). -- <<< MW -- email: see header -- voice: 49-(0)6151-6 56 83 >>>
