And to minicom, it is now working well. A small copy/paste: Directory of /dd/cmds 2008/05/12 14:42 Owner Last modified Attributes Sector Bytecount Name ----- ---------------- ---------- ------ --------- ---- 0 2006/04/21 13:38 --e-rewr 1EBF8 1B00 asm 0 2006/04/21 13:38 --e-rewr 1EBFC 1FF attr I can put the fixes for that in the startup file for the coco3/nitros9 machine. Now, I would like to be able to put something in my own rc.local that would first tune that /dev/ttyUSB1 port for the proper params, then go away and allow a "cat /dev/ttyUSB1 >/lp3" to be done, the idea being to use the linux box to convert that text into something for a modern printer which doesn't understand P.O.A. (Plain Old Ascii). I need to be able to make paper copies of program src, probably from the assembler. Suggestions gleefully checked out, thanks all. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
