I just bought a line printer which has the following three serial protocals available: - XON/XOFF - ETX/ACK - Reverse Channel (hardware flow control) I'd like to connect it to my MS-DOS 386-based system using one of the COM ports, using hardware flow control if possible. I'd also like to use the print spooler which comes with PC-Kwik (a Multisoft product). None of the documentation I have talks about how the COM device driver handles the hardware signals, and I don't recall whether it can deal with hardware signal-driven flow control. Do I have to write my own device driver, or can PC-Kwik handle this in some way that I don't know? Do I have to use XON/XOFF? (If the latter, what hardware signals need to be connected in order for data to be transmitted?) I've already spent about 6 hours fidgeting around with different combina- tions of signals and am about to go out and buy an RS232 breakout box. Send me e-mail or post information if you know how to handle this problem. FYI: the printer is a NEC L-600, and the COM port is on a no-name Taiwanese multi-feature card. Thanks! -rich
