I have another question about the plotter. If you send something illegal to the plotter, an error light will come on. If you want to find out the nature of the problem, have the computer send a certain code to the plotter. The plotter will send code back to the computer. A small program that I think should work is : echo 'code to plotter' >/dev/ttyi14 read text </dev/ttyi14 echo $text If I take away the redirection to device ttyi14 and use my own CRT as the test device, it works fine. If I use the program as written with a CRT at device ttyi14 and not a plotter, the code sent to ttyi14 will appear on the screen but when I type in some text followed by carriage return, the program does not pick it up. I have to hit carriage return two or three times before the program will pick it up. How can I get this to work like it should?
