We've done this many times with Suns, and it is pretty straightforward, but is proving difficult with our RS6000. I believe we've correctly created the device (lp0), as well as the appropriate virtual printer queue (ps0); each time we queue some output to the printer, we get DEV_WAIT as the status for the printer, and we don't see any activity on the TX serial pin. We've done continuity checks and the cable is right; we're running a pretty standard RS232 cable, and we've even swapped TX/RX with each other and tried again. We've had the device attribute "DTR=" set to both 'yes' and 'no' and it still doesn't work. And, this printer works fine from a Sun serial port. Can someone please give me a clue? Thanks.
