&R1 * Modemulator Ignores RTS
If &H is set to 1 (H/W flow control), then &R1 causes the Modemulator to ignore the incoming RTS
receive flow control signal.
&R2 * RTS Controls RXD out (default)
If &H is set to 1 (H/W flow control), then &R2 causes the Modemulator to obey the incoming RTS
receive flow control signal to enable/disable the flow of received data to the local DTE.
&S0 * DSR Override (default
)
Assert the DSR signal on the RS-232 interface for DTE applications that require it.
This does not mean that DSR will be always ON. It will be ON when the Modemulator is ready for
commands and when DCD is ON. It will be OFF while the cellular Gateway is booting or after a
disconnect while the TCP/IP Listener is starting.
&S1 * DSR follows DCD
The DSR signal follows the DCD signal on the RS-232 interface.
&W * Store RAM Variables to EEPROM
This must be the last command in the AT command string.
Settings for the following RAM variables will be stored in EEPROM:
E F Q V X
&C &D &H &I &L &R &S
{C {D {F {J {M {O {R
S0 S2 S7 S8 S19 S21 S22 S23 S44 S59 S60 S61 S64 S65
for recalling variables from EEPROM)
Also the current baud rate and parity format of the Terminal port will be saved to EEPROM which
will then be applied to the Terminal port upon power-up.
