I am in need of a multiport (probably 4 ports) serial i/o board with
full modem control lines.  I am looking for something that works with
NetBSD/i386.  On the surface, the Boca BB1004 looks promising, but it
doesn't control all the modem lines.  I am having difficulty
identifying the intersection between such boards and netbsd's drivers.

If you are using such a board or know of one, PLEASE let me know about
it so I can identify a board and eventually a source.

Thanks for your help.

Cheers,
Brook
