CHAPTER 5: Command Mode

Listing Current Operating Parameters L5 L7

The L5 and L7 commands list the current operating parameters of your modem. This information can be very useful when you are changing communications software or when you are changing modem default settings.

The command to list the Series II Modem’s current operating parame- ters is ATL5 for the basic parameters. Entering ATL7 lists additional parameters on the Modem.

Listing S-Register Values L6

Entering ATL6 lists the current values stored in the modem’s S-Register. This information can be very useful if you wish to change S-Register values. (Refer to Chapter 6 for more information on S-Registers).

Listing On-Line Diagnostics L8

The L8 command displays the current on-line CONNECT status of the Series II Modem. This display can be printed and used as a modem status report or as diagnostic information (such as when calling Tech Support). To activate this command first type +++AT<CR>(on-line escape command while maintaining command mode), then type ATL8. What then displays on your monitor is your modem's current on-line condition (e.g., Link Type, Line Speed, Serial Speed, Type of Error Correction/Data Compression, Number of past Retrains, etc.).

See Figure 5-2on the next page for a sample screen as displayed through a Windows based terminal program.
