Listing On-Line Diagnostics L8
The L8 command displays the current on-line CONNECT status status of the MMH2834. This
display can be printed and used as a modem status report or as diagnostic information (such as
when calling Tech Support).This report is given only when on-line. 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.).
