I thought i saw something about this on this group before but sgi's engineering support can't help us and suggested trying the net. what we need to do is transmit and receive 8 data bits + parity at 38.4Kbaud. we have set the stty to 38.4Kb/s; 1 start bit + 8 data bits + 1 parity bits + 1 stop bit; odd parity and the device we talk to complains of parity errors (don't believe this too much; in general, this is just an indicator of trouble). We had been driving the device correctly via a specialised terminal interface board on our terminal concentrater. does anyone have any existence proof that an SGI 4D/240 can drive a 9 bit tty port at 38.4K? please reply to andrew@research.att.com
