\C1 Enable.
\C2 Disable and Switch. Modem automatically switches to Buffer mode if it receives an error control fallback
character (an ASCII carriage return see %A command) during error control negotiation.
\D
n
– CTS Control
Clear-to-Send (CTS) is a signal from the modem to the DTE indicating that it can accept data from the DTE.
\D, \D0 Forced On. Forces CTS to always ON.
\D1 Standard RS232.
\D2 Wink When Disconnect. CTS is turned Off for 1 to 2 seconds upon a disconnect.
\D3 Follows DTR. The state of CTS follows the state of DTR.
\G
n
– Modem to Modem Flow Control
If a modem’s buffers begin to fill due to data it is receiving from the remote modem, but is not passing the data on to the
DTE, it can issue flow control messages to the remote modem. This only applies during Buffer mode connections where
the remote modem also has modem-to-modem flow control enabled. If Error Control mode is enabled, flow control
between the modems will happen automatically, regardless of the setting of this configuration option.
\G, \G0 Disable.
\G1 Enable.
