How to monitor RS-232
Hi to all,
I have a problem with my PC communicating to another PC. My PC is Linux based (SuSE 7.3) and the remote PC is DOS-based. The communications runs over RS-232.
The DOS PC controls a laser, and my application sends commands (such as: FIRE! :-)
But sometimes it goes wrong and the laser is turned off.
Is it possible to scan or monitor the RS-232 port without interferring?!?
The RS-232 port is a tty (in this case tty81a) configured as follows:
stty raw clocal 9600 -echoe ... (etc.) < tty81a
Any help would be appreciated!
Regards,
Robin...
