AT%H MNP 10 Negotiation Speed
This command allows you to determine the speed at which your modem will begin MNP 10
connections.
MNP 10 can change the speed of the connection depending upon the quality of the line. This
command sets the initial connection speed only.
By initiating MNP 10 at a lower speed you can ensure that an error correcting link is established
when this may not be possible at the highest speeds.
Refer to the chapter titled
‘ Error Correction ’ for details of MNP 10.
