Such an elaborate display of broken firmware.  Notice that we send EOP 
(via +FET), the modem then gives us garbage and resets itself nearly 30 
seconds later.  Clearly a firmware bug.  You can appeal to MultiTech 
for a fix, but in any case, you must not use Class 2 on this modem.  
Use Class 1.  We can fix bugs there.  We can't usually fix Class 2 bugs 
(we don't make the firmware).

Another fine example of broken firmware.  Notice that we send RTC and 
the modem feeds us back garbage, and again, the modem resets itself 
nearly 30 seconds later.  Use Class 1.  If you have errors there, then 
send those logs.

Whatever you do, you cannot use Class 2 on these modems with these 
firmware versions without risking these problems.  Consider your 
AT+FCLASS=? result to not contain "2".
