DTE TX-IF
Control
Mode Command:
Response:
Status:
Response: >add/DTEM_xxx'cr''lf']
>add/DTEM_xxx'cr''lf'] Where: xxx = ON or OFF.
This command configures the modem for the DTE
TX-IF control mode. If 'ON' is selected, the TX-IF
output will only be turned on if the incoming DTE
signal is asserted (also the TX-IF output has to be
programmed ON and no major modulator faults are
present). If 'OFF' is selected, the TX-IF output will
operate normal ignoring the DTE signal.
DTE Status
Command Status:
Response: >add/EDTE_xxx'cr''lf'] Where: xxx = AVA (available) or UNA (unavailable).
