&Kn — DTE/Modem Flow Control

Parameters

0, 3, 4, 5 or 6

Default3

Determines how the modem controls the flow of data between the communications software and the modem. When the modem terminal buffer is nearly full, the modem will either send an XOFF command, or drop CTS to stop the data flow. When the buffer is nearly empty, the modem will either send an XON command, or raise CTS to start the data flow.

The modem also responds to XON/XOFF characters, or RTS stimulus from the communications software by suspending or resuming transmission accordingly. The modem responds to XON/XOFF characters and also passes the XON/XOFF characters to the remote modem as data if transparent flow control is selected. When in Direct mode (&Q0), flow is not used and the modem ignores the setting of this command.

Examples

AT&K0	Disables flow control
AT&K3	Enables RTS/CTS flow control
AT&K4	Enables XON/XOFF flow control
AT&K5	Enables transparent XON/XOFF flow control
AT&K6	Enables RTS/CTS and XON/XOFF flow control
