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.
