Carl - Without getting into an excessive amount of detail, the bit banger port (the one you are using) is all but useless for serial communications under os9. This is because it is not a true serial port, but a software controlled UART emulation being done through a few bits on a parallel port. Also, there is no built-in mechanism to announce the arrival of incoming data... in effect, you must babysit the port (look for the arrival of a start bit), or possibly mangle a cable to allow an arriving character to toggle the carrier detect interrupt. There are work arounds, bu the best bet is get yourself to a Radio Shack and get an RS-232 pak (if you can still find one), They're available anywhere from $10 to $30 these days. -- Pete Lyall (OS9 Users Group VP)| DELPHI: OS9UGVP | Eaton Corp.(818)-706-5693 Compuserve: 76703,4230 (OS9 Sysop) OS9 (home): (805)-985-0632 (24hr./1200 baud) Internet: pete@wlbr.eaton.com UUCP: {ihnp4,scgvax,jplgodo,voder}!wlbr!pete
