Hi,I am running slackware 9 and attempting to communicate with a serial device over /dev/ttyS0. For testing I have plugged a female-female serial cable between my serial port and a windows box running a terminal program.I can write to the serial port, for example if I say:$ echo hi /dev/ttySO'hi' prints out on the windows machine terminal no problem.however, I cannot seem to read from it.

On Linux, I want to send a command string (i.e. Some data) to a serial port (containing control characters), and listen to the response (which also usually might contain control characters).
