4. Serial Interface Control Commands

The AT Commands described in this chapter allow the external application to determine various settings related

to the MC55's serial interface.

4.1 AT\Q Flowcontrol

Syntax

Parameter Description

[0]

(&F)

disable flow control

1 XON/XOFF software flow control

2 only CTS by DCE

3 RTS/CTS hardware flow control

Recommended for the following procedures: incoming or outgoing data calls,

fax calls, MUX mode.

Often, the initialization routine of Fax programs includes enabling RTS/CTS

handshake, eliminating the need to issue

AT\Q3 once again.

Notes

• When using XON/XOFF flow control (AT\Q1) in online mode, +++ should not be used while the data trans-

mission is paused with XOFF. Before entering the command mode with

+++ the paused transmission should

be resumed using the XON character.

• For compatibility reasons, the

AT\Q command can be used in Multiplex mode, though the settings will not

take effect. However, be aware that whenever you use the

AT\Q write command in Multiplex mode and then

save the current configuration to the user profile with

AT&W, the changed AT\Q setting will become active after

restart.

Exec Command

AT\Q[<n>]

Response(s)
