checksum. The decimal number displayed is the 8- bit sum
(from 0 to 255) of all the bytes in ROM.
ROM Checksum. The modem checks its ROM and reports
a result code of OK or ERROR.
Software Versions. The modem reports its software
versions and release date.
Modem Identification. The modem reports a configurable
identification message to the terminal.
