Hi all - I'm in the process of building a mega disk-imaging box, er really a "vintage computing support center" box to help with creating disks, imaging disks, etc. It even has a Needhams ISA rom burner (and get this, its a P4!). The computer runs Freedos as its main OS. Getting data to/from the computer isn't a problem as I have a couple 2gb USB sticks that the BIOS supports as a dos-compatible hard drive, as long as I boot with one in it. That said, I was hoping that on occasion to be able to control it from my main computer, and figured a serial cable and CTTY would work, but despite having the serial port working via Telix (can talk to my main computer running Putty), CTTY gives me a write error (and the usual abort/retry/fail). Anyone know why that is and how to fix it? I'm thinking CTTY is looking at control lines, but I have a serial breakout box on it now and cts/rts criss-crossed as they should. Thanks in advance!
