%TT - PTT Test Command
This command facilitates PTT testing of signal levels by providing continuous signals regards
of whether or not the modem is connected to the line. The signal transmitted is in accordance
with the parameter provided.
A range of commands allows the user to initiate a series of signals required to obtain PTT
approval. The signals emitted include answer tone, modulation, carriers, and other pertinent
signals. A test is initiated upon receipt of a %TTn (the second T is a password and n is a test
number), and the test is aborted when any keyboard character is entered. The modem will
continuously transmit the tone or carrier according to the parameter supplied.
