Cabletron Systems CSMIM-T1 Read All Registers, RTS/CTS Options, Sn? Read Configuration Registers

Chapter 7: AT Commands and Registers

	\Q4 enables unidirectional XON/XOFF flow control. The modem
	serial port generates, but does not respond to, XON/XOFF flow
	control characters. This setting allows for computers to transmit
	data that has XON and XOFF data characters. The computer can
	still be set to respond to XON/XOFF flow control characters sent
	to it from the modem during serial-port flow control.
	\Q5 enables unidirectional hardware flow control the same as
	\Q2, but also keeps CTS Off until a connection is established.
	\Q6 enables bi-directional hardware flow control the same as \Q3,
	but also keeps CTS Off until a connection is established and
	ignores RTS while not connected.
%Rn	Read All Registers
%R0	Displays the contents of all S registers in decimal and
	hexadecimal integers in tabular format.
%R1	Displays the contents of all :T registers in decimal and
	hexadecimal integers in tabular format.
&Rn	RTS/CTS Options
&R2	ITU-T V.13 emulates half-duplex over a full duplex line.
	Use &R2 to simulate half-duplex operation.

NOTE

The modem ignores &R during asynchronous connections.

Sn? Read Configuration Registers

Where n is an integer from 0 to 27, indicating a register, displays the contents in decimal form of the selected register.

&Sn DSR Options

&S0 DSR always on.

&S1 DSR complies with ITU-T recommendations.

Controls the Data Set Ready (DSR) signal on the serial port.
