Message Tag

TX Priority
With TX Priority set N the modem will monitor the RF Carrier frequency before transmitting.
This is to prevent data collisions. If it is being used then a random number delay timer is
started and the transmission is attempted again when this times out.
If the TX Priority is set to Y then data will be immediately transmitted regardless of whether
there is an RF Carrier detected or not. This is used in environments with large amounts of RF
emissions.
FEC
The Forward Error Correction algorithm puts redundant bytes into the data string so that it can
correct the data at the receiving modem.
Packetise Data
The Packetised Data option is set to Y and the ID number of the destination modem is set in
