I have a Boca 6-port dumb serial card, of indeterminate age, which I'm
trying to get working on a Gateway 486/33 running RH5.1. setserial
appears to initialize all six ports correctly, and I can hook up a modem
and successfully pass AT commands back and forth. The problems I'm
having seem to revolve around the speed of the serial ports.
Setserial autoprobes the ports on the card as 16550A UART's, but stty -a
always returns speed settings of 9600, no matter what speed setting I
try to pass in to the ports. I thought that all 16550A's were capable
of speeds up to 115200; am I wrong about this?
Is there any way to tell for sure what kind of UART this card has?
Thanks,
m
