I work at a lab where I write data collection programs for students. I don't know how many times I've had a student come to me and say 'Tim, your program isn't working', only to find that the problem is a device timeout error. The student(or faculty) forgot to put the printer online. Is there any way of checking to see if the printer is online, and if it's not, put it online by software control? [Tim]

Putting the printer online via software control is unlikely. However, Interrupt 17 has a function which tests online status. The only problem is that I couldn't get it to work. If anyone has a code fragment which works, could he post it?

Also, I seem to remember Prof. T. Salmi replying to it and showing that there was an easier way to do it. Our mailer and news have been a bit problematic of late and I can't find these messages on our system. Maybe someone else remembers them and has access to them still.
