The modem is on /dev/sio00, which is an ASIC emulating a 16550A, running at 38400 bps. This is the device which is dropping characters. |> Check the cabling between the modem and the port.

I haven't had a chance yet to check the cabling (it's on my list), but I suspect it's fine. I'll check it tonight, though. Andrew Chernov sent me a patch to sio.c to fix the getty problem on dialout (thanks, Andrew!), but that's only the least of the problems. The _real_ problem, and the one making it almost unusable for dialout, are the dropped characters on /dev/sio00. -- Frank Mayhar fmayhar@acsc.com Advanced Computing Systems Company 3000 S.
