For now, v123 has limited SITE EXEC capability: the command output is NOT captured and returned to the user, so you have to ensure that the command is correct before sending it.

For example, this will not work: SITE EXEC ro
But this example here will work: SITE EXEC /bin/ro

The command output goes to the serial port, instead of back to the user. I will probably leave it like that for a while (BIG JOB, lots of code bloat needed to fix).
