I was wondering if FreeBSD supported the 8-port serial cards made by
Riscom. BSD/OS does, and their intro man page describes the card as
being:
---
RC(4) BSD Programmer's Manual RC(4)
NAME
rc - SDL Communications RISCom/8 8-port serial multiplexor
SYNOPSIS
rc0 at isa? port 0x220 flags 0x0
DESCRIPTION
The RISCom/8 is an eight port EIA RS-232C (CCITT V.28) communications
multiplexor. It uses a block of 16 I/O ports selectable by on-board
switches. The block must be aligned on a 16 port boundary. The jumper-
selectable hardware interrupt level is detected during autoconfiguration
or alternatively can be specified in the system configuration file (in
this case no check is performed).

I may be receiving two of these, and would love to multiplex a bunch of
freebsd machines using serial consoles to a management machine. :) I
don't even know if these things are made anymore, but thought it would be
worth a try. I saw that the FreeBSD man pages describe two of Riscom's
high-speed serial devices, but not this device.
Thanks,
