Sounds like the [comport] probably didn't create properly. If you
have a recent auto-build or the most recent test release, then you
can send a [info( message to [comport] and get a list of the
available serial ports and their corresponding numbers. Then you
would do [comport 4] if /dev/ttyUSB0 is #4.
