As I said I reinstalled FreeBSD 4 now, so we can try solving > it there first. I've also tried running at 38400, see above. I think I've found something interesting here. As you said, the card my be emulating something with a much larger fifo. Have a look at this one: http://configure.sh/FreeBSD/serial.html This patch supports high speed serial "boards", but it might work with pcmcia serial devices as well. It supports baud rates up to 921600bps, which is what I am currently seeing com5 set up as in Windows after I updated the driver. Is it any limitations in how fast a pcmcia serial card can be set up? regards, Espen
