AT\Q Extended Flow Control

The \Q command enables you to select flow control (handshaking) between your modem and computer. While performing the same function as the &K command, the \Q command provides compatibility with Microcom modems.

Flow control is only available when the modem is configured for constant speed mode or reliable or auto-reliable modes, and is operating in on-line state.

Flow control will be ignored when your modem is configured for variable speed mode or is in local command state.
