DEC M3134-PA DS500 module

Richard, if you really need to get an ibm coax term on a pdp, there IS a way to do it. Set the 3270 style terminal to CUT mode instead of DFT. This removes much of the "smarts" from the terminal. Hook the 3270 term to a 3174 controller via coax. The 3174 controller must have the AEA option installed (ASCII emulation). Basically the AEA option gets you a number of serial ports (9 I seem to recall) on the back of the 3174 to which you can attach rs232 async dumb terminals, or, in your case, run cables to the rs232 async port(s) on a "more traditional" host. Bear in mind you will get a terminal that still won't work right with many things you might expect any terminal to work with... for example I don't believe any character (full screen) editor would work (and not just because of termcap type issues), I don't think TECO would work (esc=$).... etc. But you could do it. Most of your application programs (including system programs like login, command shell, etc) won't work either because they expect character at a time input. The basic fundamental issue is, in the IBM world what a terminal is/does and how a terminal should interact with a host system is a diametrically opposed and fundamentally different concept to how one thinks about what a terminal is and how it should interact with a host in the async/ascii world. It's much much more than just electrical and characterset issues. So... get a 3174 with option AEA and play around with it and see what you think. Jay West
