XON/XOFF Pass Through \X | Motorola V.3600 instruction

Protocols

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.

Command	Operation

\X	Process but do not pass XON/XOFF characters to
	remote DCE

\X1	Process and pass XON/XOFF characters to remote DCE

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.

Command	Operation

\G	Disable data link flow control

\G1	Enable data link flow control

Note

The V.3600 will transmit the XON/XOFF characters to start/ stop data transmission from the remote modem. The V.3600 will not respond to the XON/XOFF characters. This activity ensures that a false XON/XOFF is not detected resulting in data loss.
