Command
|
Display a four-digit product code. |
ATI0
|
Perform a checksum of the modems read-only memory (ROM) and
display the results. (This function is used only in factory testing.)
The Courier 56K Corporate modem should always display the same number
unless the flash has been updated.
|
ATI1
|
Perform a test of the modems random-access memory (RAM) and
display either OK (0) or ERROR (4), followed by OK when the test is
completed. You may want to use this command if the Courier 56K Corporate
modem appears to be malfunctioning. |

title. |
ATI3
|
Display the Courier 56K Corporate modems current configuration. |
ATI4

Display the configuration saved in nonvolatile random access memory
(NVRAM). If your Courier 56K Corporate modem connects to a device that
has Dial Security and local access enabled, you cannot view the stored
phone numbers. |
ATI5
|
Display a diagnostic summary. During a connection, the Courier 56K Corporate modem monitors and stores information about link operations.
When the call is ended, you can request a diagnostic summary.
The duration of the last call or the real time is displayed, depending
on the modem clock setting.
For calls under data compression, the number of characters sent
may be less than the number of octets sent, due to data compression
operations.
