Test Procedure
To Perform the G24-L Test
Follow the procedure below to perform the G24-L test:
1. Verify that the line modem is functioning and communicating with the computer by entering
the AT command
at in the modem’s terminal window
This common AT command prompts a properly working modem to reply
OK.
2. Verify that the G24-L is functioning and communicating with the computer by performing
the following AT commands in the G24-L terminal window:
• ati7—prompts G24-L identification
The G24-L will reply
G24-L OEM Module.
• ati8—prompts the G24-L software version
3. Make a CSD call from the G24-L to the line modem or the reverse using the
atd and ata
commands in the appropriate window
4. Verify that a connection between the two modems is established
5. Select any file to transfer between the two modems
The file can be any existing file, or a new file created specifically for the test.
6. Send the file either from the G24-L, or to the G24-L, through the terminal application using
the terminal application’s send/receive file options
7. When the file transfer is complete, use the
ath command in any of the terminal windows to
terminate the call
This step completes the test. You can now continue to perform additional tests using the same
setup, or change the setup as required.
