When I get the output of dmesg, it contains the following lines: sio0 at 0x3f8-0x3ff irq 4 flags 0x10 on isa sio0: type 16550A I knew it had to be a 16550A UART because the computer is brand new with all the appropriate bells / whistles / et cetera. Argh. I suppose I will see if I can slow down the modem now. One more question...do you think the problem is happening inside the modem itself? Or could it be caused by some kind of interference in my serial cable? I am obviously grasping here, but I just can't figure out why I am having silo errors with such a supposedly good modem (external courier v.everything 28800). >What is your dmesg output? It looks like you might have a older UART >(8250 maybe?) If that's the case, you might try slowing the modem down to >14400 and see if that doesn't help. > > >On Mon, 7 Jun 1999, Doug Jennings wrote: > >> >> After finally getting user ppp to work, I keep running into the >> following problem.
