Other Notes
The LT buffers, LT beacons and LTRACK buffer can be used even without a
GPS unit attached. You can manually set the LT buffers to any text you want (up
to 128 characters total) using the LT command:
LT 1 This is ltext buffer number 1
The LT buffers will be transmitted based on the BLT and LTP commands and
stored according to the LTRACK command even when the TNC is not in GPS
Mode.
