:report - check the identity of one or all MPSD device(s)
in the chain
:report <device number | device name>
Reports the identification of one or all MPSD device(s) in the chain.
If the command is entered without argument, all MPSD devices respond by
sending a single line of device information to the console. If a device number or
device name follows the command, that particular device responds to the
console with its identifying information.

In this example of changing the baud rate by MPSD control, the first step is to
place all of the five connected devices in MPSD mode. Next, the baud rate is
changed from 9600 (default) to 115200 for each of the five MPSD devices.
Then, the baud rate of the terminal console is changed to 115200. Keep in mind
that Device 0 is automatically selected to communicate with the terminal
console when in MPSD mode. Device 0 is responsible for echoing and relaying
MPSD commands. When out of MPSD mode, Device 0 is communicating with
the terminal console as a stand-alone unit.

The baud rate on the console can now be changed to 115200, and then:
> :unassign
disengage MPSD mode and clear out serial buffer
> :assign
re-establish MPSD communication mode

The baud rate is changed starting from the last device in the chain because after
the baud rate is set, there will be no communication between that device and the
console. Even though there is no prompt sign returned to the console, we still
