[ILUG] Serial Port Logging

[Adrian Flynn]

Hi all

Can anyone suggest a suitable package to log traffic on a serial line. I
wish to intercept data being sent to a serial printer and log it to a file.
The data would then be retransmitted to the printer on a second serial port.

I suspect that this might be as simple as a bash script copying from ttyS0
to stdout, piping the output through tee and subsequently redirecting the
output to ttyS1, but I am not sure how to set this up.

Thanks for any suggestions

Adrian
