I have to agree. I've been using various cards with good luck that way, even something as complex as a 7210 based HP-IB card. In general I think that industrial I/O is a very slim market, where almost every single application has unique needs, and any attempt at generalizing a driver for these kinds of cards and applications is a waste of time. <DETOUR> Let me add that a 8-port relay card makes a very nice remote-reset gadget. I have a small 486 machine with 8 sio ports and an 8 port relay card connected to my machines here in my lab. The relays are connected to the RESET pins on the computers. Real nice. All done from userland. </DETOUR> -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
