Ulf Kieber stands accused of saying: > we currently discuss buying a multi IO card, and I'd need some help to > make the proper decision.

You may have a (slightly) better time if you try talking to a supplier that handles the industrial control business, or one that's into SCO systems 8) > We had an offer for a BocaBoard 1004 and BocaBoard 1008, both not > usable for our purposes, because they are lacking modem control.

Stay away. > I'd like to hear, if there are any other cards available (I think > there is at least an AST 8 port card I'd like to see documentation > for), meeting the following requirements: There's a number of 8-port AST compatibles that work quite well; you can get them with 16550's already onboard.

The cards come with D37 to D-25 adapters, so you do eventually get the D25's. > - should of course be supported by FreeBSD. :) There's ten or so sites around here using them with no trouble at all. > Rodney Grimes told me to look into the BocaBoard 2016, but asked me to > verify if it meets our requirements. The boards in use here are PC-COM boards, the "8 port RS232 FIFO card" > Ulf Kieber Hope that's of some use. > Don't expect me to be a breeder, and I won't assume you're a fag.
