[rescue] Sun SBus serial cards

[Mark Price]

Hi Doug,


So, you need more async serial ports than the two that came on the system?

Yes, I'm starting an ISP with dial-in modems, and I currently just have a
Sparcstation.

I think you're right, I found the manual for the Sun HSI card, and it can't
speak "low speed" serial RS-232.


What most people did needing more async serial ports than 2 was to run a

Thanks for the tip, I'll check into Xylogics.. I actually have a Xyplex
terminal server, but it has been a total pain to work with.  I know Cisco
had the AS5300 with digital modems, but I'm not familiar with their other
terminal server options, I'll check it out.
