Hi. I would think that your CRON is not running or there is something up
with the timing job that was entered (That's just a guess).  *Make sure
that your pi is updated with sudo apt-get update and then sudo apt-get
upgrade.

There's a couple of ways to get a picture of what's going on, the first
thing is to turn on the cron logging and then look at it's log with the
command: less /var/logs/cron.log and see what it is reporting.  And then go
to correct the spelling or 
whatever the cause is. Check the doc under "debugging the cron
timer" to see how to turn it on.

Another approach is to see if the script,itself, is working.  Manually
issue the script command with ./startSerial (if that's the name you called
your script).  Perhaps you never made the text file executable.

Finally, if the script is working, bypass it and manually type: tcpser -s
2400 -d /dev/ttyUSB0 &

at the bash and then issue a "ps -A" the tcpser should be in the
list near the bottom.  If it is, then issue the ps -x | grep -v grep |grep
-c "tcpser" command manually to see the result.  That should tell
you if the tcpser command is working, itself.
