Could I ask to see some sample code for the COM port commands? I've searched the past few years help digests, and your guidance for Dr. Rusciano (quoted below) is what I could find... I'd like to follow up.
The EMOTIV+ EEG software we have can listen to COM1 or COM2, and can take in one code... Thus far it only works (sending from another program, SuperLab) when I set parity to odd. The OpenCOMPort() command has parameters for number (do I just say "1" for COM1?) and baud rate, but not sfaict for parity or handshaking. I would really like to be able to present our stimuli using PEBL instead, but clearly I could use some help with the serial port part.
