Protocols

Note

The Modem 3600 will transmit the XON/XOFF characters to start/stop data transmission from the remote modem. The Modem 3600 will not respond to the XON/XOFF characters. This activity ensures that a false XON/XOFF is not detected resulting in data loss.

Break Control \Kn

Use \Kn (n = 0-5) to indicate the action taken by the modem when a break is encountered.

Command	Operation

\K	Break option 0

\K1	Break option 1

\K2	Break option 2

\K3	Break option 3

\K4	Break option 4

\K5	Break option 5

Conditions under which breaks may occur are explained below with descriptions of the modem's response under the different \K command break options.

A break is sent to the serial port while the modem is in connect state during a reliable or normal connection (no protocol, data buffered).

Command	Operation

\K, \K2, \K4	Enter command mode but do not send break to the
	remote modem

\K1	Empty the data buffers and send break to the remote
	modem

\K3	Immediately send break to the remote modem

\K5	Send break to the remote modem in sequence with any
	data received from the serial port
