Hi All.
I have a very remote system that has been working for over 18 months without
problems. I SSH in and admin/fix whatever this way.
Unfortunately, I have an unusual problem(s) with TS-SER4 ports initialisation
now and it is holding up a 24/7 monitoring system so I am rather concerned
about it.
My test script is:
<code>
:root# cat ./TS-SER4.sh
#!/bin/sh
cat /proc/tty/driver/serial
date
. /initrd/ts7800.subr
pc104on
modprobe ts7800_isa16550 irq=6 io=0x3e8
rmmod ts7800_isa16550
echo; echo "COM3 Installed"
modprobe ts7800_isa16550 irq=6 io=0x2e8
rmmod ts7800_isa16550
echo; echo "COM4 Installed"
modprobe ts7800_isa16550 irq=6 io=0x3a8
rmmod ts7800_isa16550
echo; echo "COM5 Installed"
modprobe ts7800_isa16550 irq=6 io=0x2a8
echo; echo "COM6 Installed"
cat /proc/tty/driver/serial
chown -R root:cla /dev/ttyS*
chown -R root:cla /dev/ttyUSB*
ls -l /dev/ttyS* /dev/ttyUSB*
date
</code>
and as you can see (below) from the output the TS-SER4's don't get initialised
correctly (if at all). This test shell has been used since I had the TS-SER4
cards (>year) so it works, but even if I carry out each modprobe & rmmod
instruction pair manually I still get the same results. NB: The h/w is in a
locked cabinet (with intruder alarm) so the jumpering should be the say as its
always been: IRQ2+IRQ4 and COM1+COM2.

Apart from a possible h/w fault (and I have to travel a long way) has anyone
experienced any like issue and found a solution that I can try before embark on
a long voyage?
Feedback much appreciated.
