I0 The modem returns a 4-digit product code. If you have a problem and call U.S. Robotics' Technical Support Depart- ment, you may be asked for this product code.

I1 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.

I2 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.

I3 The modem returns the duration of the last call if set to K0. It displays the actual time if set to K1. See the description of the Kn command in Chapter 4.

I4 The modem displays its current configuration. Figure 6.1 on the following page is an example.
