Hi folks...

I've written and just committed a driver for PCMCIA multi-port serial
cards.  Currently, only the Socket Communications, Inc. Dual Serial card
is supported, but adding support for others (e.g. Intel 4-port serial
cards) should be easy.

pcmcia1 at pcic0 controller 0 socket 1
pcmcia1: CIS checksum failed
pcmcom0 at pcmcia1 function 0: Socket Communications Dual RS232
pcmcom0: slave 0 port 0x110-0x117
com3 at pcmcom0 slave 0: ns16550a, working fifo
pcmcom0: slave 1 port 0x2e8-0x2ef
com4 at pcmcom0 slave 1: ns16550a, working fifo

I'm currently typing over a Metricom Ricochet connected to "com3".  The
performance seems quite acceptable :-)

If you have other PCMCIA multi-port serial cards that you want to have
supported, drop me a line.
