I am developing some software on Windows which will run on Linux on an embedded ARM processor.
It will take a few weeks until the hardware arrives, but I would like to test the software now, in order to be prepared.
Is there some gratis software or Windows (preferably, but I could accept Linux), which:
detects any output which my program write to the serial port and displays it, so that I can verify it
allows me to input text to the serial port, so that I can verify that my app receives it correctly
must support 9900, 8, N, 1, but I don't object to flexibility & being able to specify other values :-)
preferably with GUI, but command line is also acceptable
scripting (reply to output X with input Y would be a big bonus)
