Is there any way to activate a program on the HP-48sx from a carrier
detection on the serial port? I want to make a program that will automaticaly
keep track of how long I am using the phone on the calculator. I have the
timing program ready. Now, all I need is some way to have the computer
automaticaly activate the program on the calculator whenever it get's a
carrier detect on the serial port. Any ideas anyone?
