Should I use >/dev/tty1G instead of /dev/tty1g? Use the modem control port (the driver uses DTR when you refer to the modem control port). Wire the busy or ready line from the printer (usually 11 or 20 on a 25 pin connector) to CTS on the computer port (pin 5 on a 25 pin connector). Change your stty to turn OFF xon xoff and clocal, turn ON rtsflow and ctsflow ( stty-ixon -ixoff -clocal rtsflow ctsflow ). If you are using 2.3.1 make sure that you apply the ctsflow/rtsflow fix from SCO Support. -- **************************************************** Eli Levine Robec Distributors rutgers!bpa!temvax!robechq!eli ****************************************************
