Epson Multi-mode Data Controller MFJ-1278B - Manual (Page 192)

MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS
BWNL ON/OFF Mode: AMTOR Default: OFF
BWNL controls whether the MFJ-1278B in mode B FEC waits for you to send a newline
character ( <CR> ) before it starts transmitting the data.
If BWNL is OFF then every character you transmit in mode B will be sent as soon as
possible.
If BWNL is ON, the MFJ-1278B will buffer the entire line sending it only when you have
completed it, and pressed the RETURN key. This willallowyou to fix typing mistakes before
transmission. If the end of the line comes before you finish, then the line is automatically
sent.
CALIRA Mode: All
CALIBRA is an immediate command, and is used to transfer control to the modem
calibration routine. Calibration may be performed at any time without altering the current
link state.
Briefly, the commands available in the calibration routine are:
<SPACE>
Switches between the Mark and Space transmit audio tones.
D
Alternates between the two transmit tones at a rate determined by the radio baud rate. This
will help you to calibrate the demodulator.
K
Activates the modulator and Toggles the PTT line on/off.
Q
Quits the calibration routine, and returns to command mode.
