When the modem is powered on,
the unit momentarily displays the
power-on screen, which typically
looks like this:
V.32 bis/19.2M
Version 3.02
The numbers displayed in the
lower right corner are the revision
levels of the software used in the
modem. The software revision
levels displayed by your unit may
be different than those shown
above. If you need to call Technical
Support, please be prepared to give
the support group the software
revision levels of your unit.
The modem spends about two
seconds checking the ROM
checksum and doing self-tests and
then displays the EIA status screen.
