Nn - Activation of automatic mode.
Introduction
Parameters
This command activates or deactivates detection of automatic mode. The parameter value, if valid, is written in bit 1 of S31.
The parameters are:
Code
N0
N1
Description
Detection of automatic mode is deactivated (equivalent to giving the 0 value to the sub-parameter +MS). The handshaking which follows is made according to the content of S37 or, if S37 is at 0, according to the most recently detected
DTE baud rate.
Detection of automatic mode is activated (equivalent to giving the value 1 to the sub-parameter +MS). The handshaking which follows is made according to the automatic mode algorithm supported by the modem, in other words according to the content of S37 or, if S37 is 0, by starting at 28800 b/s V.34 (RC288). This command also equates to F0 (RC144) (default value).

The Nn and S37=x commands have priority over the values of the +MS command. When the N0 or N1 command is sent, the sub-parameters of +MS are updated to reflect the values of Nn and S37 (see descriptions of the +MS command and of the S37 register).
For example: z N1S37=10 updates the sub-parameters of the +MS command as follows: z
+MS=10,1,300,12000
N037=10 updates the sub-parameters of the +MS command as follows:
+MS=10,0,12000,12000
2.
It is recommended to use the +MS command rather than the Nn and S37=x commands. The Nn and S37=x commands are supported to ensure compatibility with the existing communication software.
