XON/XOFF Pass Through \X
This option is active when flow control of the modem by the DTE has
been selected for XON/XOFF and the connect mode is MNP-only or
normal. It enables or disables sending local flow control characters
(XON/XOFF) to the remote modem as well as being acted on in the
local modem. In MNP-only mode the modem treats incoming XON/
XOFF characters from the remote modem as data characters. In normal
mode the modem will look at the \G command and act accordingly.
IMPORTANT: With \X1 in effect, local flow control characters are
sent to the remote system. These characters may turn on the data flow
from the remote system before the modem is ready to receive more data,
possibly resulting in data loss.

Data Link Flow Control \G
This flow control paces data from the remote modem to the local
modem during a normal connection. When the \G1 command is sent,
the modem uses XON/XOFF to start/stop data transmission from the
remote modem. This command is ignored during an MNP connection.
