Lines: 22 Distribution: world Message-ID: <330pqq$cr7$1@heifetz.msen.com> References: <1994Aug17.042726.2055@atlas.com> NNTP-Posting-Host: 192.245.33.55 The DigiBoard series of multi-port serial boards are not supported under FreeBSD. Unless they have the same interrupt sharing mechanism as the AST boards, or are similar to the BocaBoards. I have a FastComm 4W 4-port board that is not explicitely supported by FreeBSD, but it does work fine. The board is not used under high-load situations (the machine it is on is relatively passive), so I have no performance data. It does support up to 115.2 kbps, though I use it as 4800 and 9600 bps. I had to put a hack into 1.1.Beta to get it to work there (thanks to Bob Wilcox for providing that hack). It was incorporated into 1.1.5, and possibly 1.1. If the multiport board that you are interested in has one shared IRQ, I'd say that chances are that you can get it to work, with some (possibly alot) of elbow grease (sio.c is not that complicated if you know something about IRQs and serial chips). -Mark Taylor mtaylor@cybernet.com
