the base sends the following message back to the host:
*
?CR
 If the Base Station receives more than 231 characters, it treats that
statement as an Illegal Command. If it sees more than 231

the Terminal and shuts down:

You can re-initialize the terminal by sending *@EOT or by
powering the base off and back on.
Automatic Check Back
When a terminal checks back in to see if there is a change in instructions,
the host can send back the same prompt or send back a new prompt. The
check back occurs according to the time specified in the Terminal's setup,
(specified in increments of 5 seconds). When a check back occurs, the
Terminal clears the screen of the current prompt, and sends back the
following message:
Byte position Function Possible values
1 RF Terminal ID 0-9,A-Z,a-z,-=
2+ Check Back BEL (ASCII 07)
Last Termination of message CR (ASCII 13)
Base Station Initialized Message
Whenever the Base Station is powered up, it sends a message back to the
host as follows:
Byte position Function Possible values
1 BASE ID * (Base ID is fixed)
2+ Base Initialization DC3 (ASCII 19)
Last Termination of message CR (ASCII 13)
