Hi

I'm trying to send <CR> and <LF> signals over a serial line to a serial
GPS unit.
I was thinking about how to do this - can I just write <CR> and then
the software will interpret it as a real <CR>-sign? Or will it think
that <CR> are just another 4 letters to be transferred?

I forgot to say:

Linux distribution: Fedora Core 5

Serial Terminal software: GTKTerm, or using:
echo '$GPGLL<CR><LF>' >> /dev/ttyS0
GPS-unit: NXPro3 GPS-601 (using the NMEA-0183 communication
standard)

echo -ne "$GPGLL\r\n" >> /dev/ttyS0

Read the man page for echo.

Assuming you're using the Bash shell, 'help echo' will tell you what you
need to know.
