Unsolicited Firmware Updates
We want to emphasize that this diagnostic option should be executed only
when instructed by a Nextel Customer Care Representative. However, there are
certain sequences of events that will prompt you for a firmware update.

The following lists the sequence of events that will
cause HyperTerminal to prompt you for firmware
update.
1 Modem is OFF (all cables are connected except for the
power connector).
2 The computer is ON and the HyperTerminal is active.

the power slot).
