92 MultiModemISI Hybrid Series, ISIHP-2S/2U/4S/4U/4SD

Modem AT Commands & S-Registers

which uses the Request to Send (RTS) signal on the RS-232/V.24 interface.

Hardware flow control cannot be enabled unless an active error correction

protocol is selected. This is the factory default setting. (This is the same as

&K3.)

\Xn XON/XOFF Pass-Through

n = 0, 1

Default: \X0

When XON/XOFF pacing is active, the local modem has two options

regarding the XON and XOFF characters. It can respond to and discard the

characters from the computer, or it can respond to the characters and pass

them through the data communications link to the remote modem, thereby

pacing the remote modem as well.

\X0 causes the modem to respond to and discard the XON and XOFF

characters (default)

\X1 causes the modem to respond to and pass on the XON and XOFF

characters

\Jn Data Buffer Control

n = 0

Default: \J0

\J0 disables force line rate less than or equal to DTE rate

\J1 enables force line rate less than or equal to DTE rate

\Kn Set Break Control

n = 0, 1, 2, 3, 4, 5

Default: \K5

Determines how the modem processes a break signal received from the

local DTE during an online connection.

\K5 causes the modem to send the break to the remote modem in sequence

with transmitted data, non-destructive, non-expedited.

Escape Sequences

Escape sequences are also known as escape codes. They are used to cause
