[time-nuts] Serial Port Logging Script?

[Jason Rabel]

Yeah I think I kind of jumped the gun after doing a little more
investigation... The board is outputting a CR and LF so technically the
logserial program isn't wrong.

I really didn't want to leave a terminal program open for various reasons.

I might write a perl script later on, it would be nice to timestamp each row
too. Something to add to my to-do list.

Most terminal programs have a log-to-file option.

Is that a CR vs CR/LF mixup?  If so, record it however you can and clean out

the LFs later.  I used to have scripts that converted from one mode to 
another.  I think one used sed and the other used awk.

If it really is an extra blank line, that should be reasonably easy to
filter 
out.
