Re: serial port crashes
Thanks for the help.
I pulled the computer apart, and the modem (Com2) is set to IRQ 03, the
mouse port, which is set in the BIOS (Com1 -> TTYS0) is set to IRQ 04.
The boot messages seem to reflect this:
Nov 12 16:00:17 debian kernel: Serial driver version 4.13 with no serial
options enabled
Nov 12 16:00:17 debian kernel: tty00 at 0x03f8 (irq = 4) is a 16550A
Nov 12 16:00:17 debian kernel: tty01 at 0x02f8 (irq = 3) is a 16550A
So it looks like the mouse and modem are on different IRQs.
I've attached the portion of /var/log/messages from the pppd going up,
through the crash, through the reboot. Let me know if there is any more
information that would be useful.
I _really_ appreciate the help. This has been driving me crazy ! :-)

Only lovers laugh.
Others grin and bear it,
and some there be who bear it,
and are unable to grin.
