[time-nuts] Serial port server .. any interest in a writeup onusing ?

[DaveH]

I used to run a multi-line BBS (Wildcat!) and may still have two multi-port
serial interfaces.  I know that one has eight com ports and the other can
support 64 but only has 32 ports installed.

Give me a day or two to dig them out (if I still have them) -- they were
both working fine when removed from service and Drivers are available (just
checked their website).

PCI bus. DB-25 connectors.
