Hello again. Does anyone out there in Sys V know what the correct procedure for openning a two-way connection to a serial device is? I want to be to send ascii strings to a few devices and read results back, but every time I fiddle with all of the various stty type values, I get various results -- all wrong. How can one for example, write a C program which will open a 2400 baud connection to a modem on /dev/tty0, send the string "AT<return>" and then attempt to read the "OK" from the modem? Sounds trivial, but it hasn't been for me!
