and the terminator that signals the end of the
command.
Example: Command to set the VFO A to 7 MHz

For example, note the following in the case of the above
FA command (Frequency of the VFO A):
• To set the frequency to 7 MHz, the following
command is sent from the PC to the transceiver:
"FA00007000000;"
• To read the frequency of VFO A, the following
command is sent from the PC to the transceiver:
