Link diagnostics summary
The modem returns a 3-digit product code. If you have a
problem and call USRobotics' Technical Support Depart-
ment, you may be asked for this product code.
The
modem performs a checksum of its read only memory
(ROM) and returns the result to the screen. This function is
used only in factory testing. The modem should always
read the same number.
The modem performs a test of its random access memory
(RAM) and returns either the OK (0) or ERROR (4) result
code, followed by OK when the test is completed. You may
want to use this command as a checkpoint if the modem
appears to be malfunctioning.
The modem returns the duration of the last call if set to KO.
It displays the actual time if set to Kl. See the description of
the Kn command in Chapter 5.
The modem displays its current configuration.
