Controlling Link Speeds; Limiting The Highest Possible Connect Speed - US Robotics 000698-13 Getting Started Manual

Controlling Link Speeds

You can use the &N and &U commands to control the link speeds of your
I-modem with x2. Use the following table to determine how to use &N
and &U commands:
To limit the
Highest possible connect speed
Lowest possible connect speed
Range of possible connect speeds
Note: The default values for &N and &U are 0. If you change these values,
you will limit the speeds at which you can connect. U.S. Robotics
recommends that you do not alter these values.

Limiting the Highest Possible Connect Speed

The &N command allows you to limit the highest possible connect speed.
If a remote modem attempts to connect to your Courier with x2 at a speed
higher than &N, your Courier with x2 will not allow it to connect.
