RTS Operation G-5
Command: #1RT2
Response: *1RT2+00550.00E6
Read Time Delay 3 (RT3)
The RT3 command is used to read the time delay value previously stored
with the T3 command. The value returned is scaled in milliseconds and has
a range of 0 to 2000ms.
Command: $1RT3
Response: *+00035.00
Command: #1RT3
Response: *RT3+00035.00E5
Request-To-Send+ (RTS+)
The RTS+ command enables the RTS output function and sets the active
signal polarity to high (positive voltage). The RTS+ command should be
selected for modems that require a positive signal level to enable the
transmitter. During the idle state, while no data is being transmitted, the RTS
output terminal will be low (zero volts).
The RTS+ command is write protected and the polarity value is stored in
EEPROM memory. Therefore, all subsequent power ups will activate the
RTS+ mode eliminating the need for software initialization. The RTS+ mode
will remain active until the module receives a RTSD command.
NOTE: The RTS output function will override any alarm or digital output
commands associated with digital output 0.

Request-To-Send- (RTS-)
The RTS- command enables the RTS output function and sets the active
signal polarity to low (zero volts). The RTS- command should be selected
for modems that require a low signal level to enable the transmitter. During
the idle state, while no data is being transmitted, the RTS output terminal will
be high (positive voltage).
