I
Identication
The I command asks the modem for information that can be used to determine the modem’s compatibility with other
software and to ensure the modem is operating properly.
I0
Display product code. The modem reports its product code to the terminal. The modem produces
information text dependent upon its features and capabilities.
I1
Display ROM checksum. The modem reports the value of its ROM checksum. The decimal number
displayed is the eight bit sum (from 0 to 255) of all the bytes in ROM.
I2
Test the ROM checksum. The modem checks its ROM to ensure it is correct. The modem reports a
result code indicating whether the ROM is OK or in ERROR.
I3
Display Software Versions. The modem reports the modem controller and data pump software
versions, and the modem controller software release date, to the terminal.
I4
Display Modem Identication. The modem reports a congurable identication message to the
terminal.
