I've got an ..... *odd* situation here, and I could use some help. I'm trying to attach an Apple Imagewriter (old style, Model A9M0303, P/N 825-0568-A) as a standard serial printer on my PC clone running Xenix (2.3.2, '386). Why am I doing this, you may very well ask? Well, I blew all my money on the Xenix system, and my housemate has this perfectly good Imagewriter, and I _really_ wanted to be able to print stuff out. Anyway, I connected it up with a 25-pin cable, using pins number 2, 3, 7, 8, & 20. It works fine, with one execption. I seem to have a flow control problem. After about one page of printout, stuff gets incredibly garbled, and eventually stops printing. I set up the Xenix side to use xon-xoff flow control, but the Imagewriter doesn't seem to be using it. Hence, the following questions: 1) Can an Imagewriter be set up to use xon/xoff flow control? If so, how? (Best) 2) Does an Imagewriter use ready/busy (RTS/CTS) flow control? If so, does it use pins 4 & 5 or does it use pin 20? (Acceptable) 3) Has the Imagewriter been set up by Apple to use some sort of bizarre Apple-esque flow control scheme, and thus rendered unusable by any other form of hardware in the known uninverse? (Worst) The Imagewriter has no the standard "no user-servicable parts inside" message, so I don't want to do anything too drastic. Plus, it's not mine. All help, advice, suggestions, etc. appreciated. AtVhAaNkCsE,
