The USB to serial are known to be sort of flaky... Saying that, the
hardware should be powered fine with that power source you have.

If you set it up as a service, it should restart automatically if you told
it to in the service file.

To find out if tcpser is still running after it craps out, at the bash type:
ps -ef | grep tcpser

If the resulting list displays that it is still running, then kill it by
its PID.  Don't confuse the "grep tcpser" in the list as the
tcpser command, itself.

If it is not running, then I'd write a quick script that will perform that
ps command above and if tcpser does not exist, then start it. Put an entry
in your CRON to run that script every 5 minutes or quicker.

Still, the best practice would be to make a tcpser service and tell the
service to restart on termination.
