I already have powerup state set for no command echo or response
codes. The problem with with the ring detect line. Apparently, the
SCO tty drivers don't know how to handle the ring detect interrupts,
and barf when they get them. I have been informed that there is a fix
(xnx128) for this from SCO:
Dear SCO Customer,
Enclosed is Support Level Supplement (SLS) xnx128. This floppy
contains a set of modified SCO XENIX files which will allow an
internal modem to answer incoming calls. Previously the error
message "Garbage or loose cable on serial dev <x>, port shut
down" was displayed on the console when ever the modem attempted
to answer a call. Serial dev <x> is either a zero or eight.
Zero for /dev/tty1a (COM1), or eight for /dev/tty2a (COM2).
This supplement is for SCO XENIX 286 Operating System Release
2.2.3 and SCO XENIX 386 Operating System Release 2.3.0, 2.3.1,
2.3.1 only. In order to install this supplement, the Link Kit
must be installed. If the Link Kit is not installed on your
system, or if you are not sure, refer to custom(C) in your SCO
XENIX System V Operating System User's Reference manual. To
install this supplement, please follow the steps outlined below:
1. Login as root.
2. Make sure that you are in the root directory.
cd / <RETURN>
3. Type the command:
/etc/install <RETURN>
4. Type "y" at the prompt for the first floppy.
5. Follow the instructions on the console.
6. Reboot the machine using the reboot(C) command:
/etc/reboot <RETURN>
