I work with a local school, and several of the local kids have really gotten into Unix. Specifically, they're big fans of the old "heavy iron" approach to computing, so we've built a FreeBSD server system with four serial-connected terminals. Specifically, we've gotten our hands on an old VT100, two LSI ADM 5, and an old laptop. I've verified that all four terminals are indeed working.
Most modern motherboards don't include RS-232 serial ports, so I bought this little baby from Newegg. It's a SYBA PCI 4-port serial card, model SD-PCI-4S. Under the hood, it uses the NM9845 chipset.
The system runs FreeBSD 8.0 AMD64. pciconf -vl reports the card as:
I have puc(4) compiled into the kernel, which reports it as
in dmesg.
Unfortunately, no serial device entries can be found. sio(4) doesn't compile on amd64, but I've seen posts saying that uart(4) works with this chipset. Unfortunately, when I compile in or kdload uart, nothing detects.
Me and my students would be very greatful for any advice in getting this card to work.
