Multitech MT5634ZBA-USB manual Modem Port Flow Control, Data Buffer Control, Break Control

	Chapter 4 - AT Commands, S-Registers and Result Codes
Command: \Gn	Modem Port Flow Control
Values:	n = 0
Default:	0
Description:\G0	Returns an OK for backward compatibility with some software.
\G1	Not supported—responds ERROR.

Command: \Kn	Break Control
Values:	n = 0–5
Default:	5
Description:	Controls the response of the modem to a break received from the computer, the remote

	Data mode. The modem receives the break from the computer:
\K0	Enter online command mode, no break sent to the remote modem.
\K1	Clear data buffers and send break to the remote modem.
\K2	Same as \K0.
\K3	Send break immediately to the remote modem .
\K4	Same as \K0.
\K5	Send break to the remote modem in sequence with the transmitted data.
	Data mode. The modem receives the break from the remote modem:
\K0	Clear data buffers and send break to the computer.
\K1	Same as \K0.
\K2	Send break immediately to the computer.
\K3	Same as \K2.
\K4	Send break to the computer in sequence with the received data.
\K5	Same as \K4.
	Online command mode. The modem receives a \Bn command from the computer:
\K0	Clear data buffers and send break to the remote modem.
\K1	Same as \K0.
\K2	Send break immediately to the remote modem.
\K3	Same as \K2.
\K4	Send break to the remote modem in sequence with the transmitted data.
\K5	Same as \K4.
Command: \Nn	Error Correction Mode Selection
Values:	n = 0–5, or 7
Default:	3
Description:\N0	Non-error correction mode with data buffering (buffer mode; same as &Q6).
\N1	Direct mode.
\N2	MNP reliable mode. If the modem cannot make an MNP connection, it disconnects.
\N3	V.42/MNP auto-reliable mode. The modem attempts first to connect in V.42 error correc-
	tion mode, then in MNP mode, and finally in non-error-correction (buffer) mode with continued
	operation.
\N4	V.42 reliable mode. If the modem cannot make a V.42 connection, it disconnects.
\N5	V.42, MNP, or non-error correction (same as \N3).
