A telemetry beacon is sent every n*10 seconds. If n = 0, the beacon is disabled. The
telemetry beacon is a UI frame sent to BEACON. If there is a current UNPROTO
digipeat path, it will be used to transmit the telemetry beacon.
The data in the UI frame is in the form: ―T#nnn,an0,an1,an2,an3,an5,bbbbbbbb‖, where:
―nnn‖ is a decimal count for the telemetry beacon and is incremented each time the
beacon is sent. When first used, or after the unit is reset, the beacon counter begins
at 001 (T#001). After reaching 999 (T#999), the counter cycles around to 000
(T#000).
―an0", ‖an1", ―an2", ‖an3", and ―an5" are the decimal readings on the corresponding
analog inputs of the 68HC11F1 (the KPC-3 Plus microprocessor).
Note: APRS expects leading zeroes for the analog readings; you must set
RANGE to 0-255 to use the APRS format.
―bbbbbbbb‖ is the binary reading of the 8 pins on PORT E of the 68HC11F1 (PORT
E is a shared port with the analog inputs), where ―b‖ = ―1" means a Logic High on the
pin and ‖b" = ―0" means a Logic Low on the pin. The first ‖b" in the string of 8 binary
digits is the most significant bit of PORT E and the last ―b‖ is the least significant bit
of PORT E.
Hint: For details on the 8 pins on PORT E, see the KPC-3 Plus schematic.
See the documentation on APRS for more information on the use of telemetry along
with GPS.

TRACE {ON | OFF}
default OFF
When ON, all received frames are displayed in their entirety, in hexadecimal, including
all header information. All packets, which are eligible for monitoring also, will be
displayed in normal text.
TRANS
immediate
This command causes immediate exit from Command Mode into Transparent Mode.
The current link state is not affected. There are no special editing characters, all
characters are sent out as received. To get out of Transparent, send the TNC a modem
break if BREAK is ON, or see CMDTIME for a special keyboard sequence.
