Problem:
OpenBSD 4.2 on i386
Serial port /dev/cua00 connected to the console port on a firewall.
I need to catch all text output from the serial port to a file.
The process doing this must survive a loss of network.
The box is running headless.
I could suggest you run cu in a screen session. I have used
cu ... | tee logfile
in the past, but there are possibly more elegant solutions
I've never tried using tee(1) but it is more elegant than using the
default solution provided by tip/cu/remote.
I use 'script'. It gets EVERYTHING. You have to do a little post-
processing, but it works very well.
However, if you're saying that you want to capture all output on the
firewall coming in to /dev/cua00, why not just open the device and
read from it? 'tail -f /dev/cua00 > logfile' would do this. Assuming
that you have the line dedicated to this and don't need to provide any
input.
If you want to use 'cu', you could also investigate the 'record'
variable. (~s record /path/to/logfile)
