1.10 Messages from the Radio
The following messages are sent from the radio to the PC in conventional
mode. Some are solicited by commands from the PC, while others are
unsolicited and are sent because of changes within the radio.
The prompt character ‘.’ is returned to the PC immediately after receiving a
command to signify that another may begin. If the command initiates a
return message, then when the return message has been sent the radio sends
another prompt.
If the radio sends an unsolicited message, it sends a prompt after the message.
