I have just hit a MAJOR problem with VP/ix running on SCO XENIX
2.3.3. I have an application that needs to use a modem, so I
mapped (in vpix.cnf) COM1 to /dev/ttya7. The modem is connected
to a Texas Instruments CB811 8 port mux (which doesn't support
modem control 8^( ).
As soon as VP/ix is run with COM1 defined, the system crashes
with an entry in /etc/messages about an unrecoverable kernel page
fault. This also happens when I define COM2.
The VP/ix manual says that you cannot have COM1 defined to a
Xenix device that is also a serial terminal. So I thought of
disabling the modem port before invoking VP/ix. No luck..it
still crashed.
I suspect that this may be a problem with the CB811 mux, which I
believe is a Computone that is OEMed by TI. Has anyone had any
experience like this and solved it? Thanks for any help you can
offer.
