You can test by running "cu -l /dev/cuaa0" and see if an > "ATZ" gives you "OK" back. If not, try /dev/cuaa1. The key is the first line: sio0: configured irq 4 not in bitmap of probed irqs 0 This really means that BIOS need to be used to enable the port. Until then, it will simply not work. Since this is an IBM computer, you may need a DOS utility to enable the port, but my only experience with IBMs of newer vintage than the AT is with laptops. It turns out that when the serial driver (if_sio) can't talk to the device, it labels it as an 8250. I really, really will write a patch to correct this soon, although it's too late to make 4.5.
