...so the phone rang and both the modems answered but no login
so I get in the car and dash over to the office (sunday night,
right, but what else is new) and the system seems fine -- TR is
high on both modems showing that DTR is asserted. The line is enabled.
One modem is dial in only so what is going on??? I don't know, but
to get the system up again I log in as root and /etc/haltsys. The system
comes up and now everything seems hunky-dory.

Do I suspect the archive tape drive card recently added to my system?
Well, it's jumpered for I/O address 220H, IRQ3 and DMA channel 3. 
The connect Tech board is using IRQ 10 (=SCO vector 26) and memory map
I/O to a000 as usual so there's no conflict, is there?
(In case you ask, I don't have a COM1: COM2: card -- COM2: apparently
uses IRQ3 -- yes, I rely on the connect Tech for *ALL* my  serial I/O)
Anyway, I've been able to call in successfully to the system with
the archive board installed.

Anyone have any comments?

You know, when I looked at /usr/sys/conf/master I saw that the "spl"
level for driver "sio" is 7, way below other things. Is that appropriate?

Anyone got any answers?
