According to tech the serial port can run at 230K. And stty 230400 appears to work.
On my pc if I run pppd at 230400 I don't get a connection. Anybody had any luck
connecting at 230K?
I first tried using setserial to set 230K with spd_shi but the kernel popped
out a deprecated message. Either way, I couldn't get it to work.
