Although Specialix deal in intelligent I/O controllers, we do have a
dumb 4-port:
``The Specialix I/O4 is an entry level 4-port serial interface expansion
card, with full modem control. Compatible with the AST Fourport/XN
board, it supports terminals, modems and other serial devices.''
MODEL DESCRIPTION LIST PRICE
I/O4 Non-intelligent, 4-port card $ 300
These boards use 16C450 UARTs, which aren't socketed. We have a few of these
in stock here in the US office. I don't know if the other Specialix offices
have stock at the moment.
Initially, contact me here (jonb@specialix.com) for information.
