Yeah,  the problem is that AT+FRM=146 should *not* result in OK.  The OK 
result indicates a return to command-mode.  AT+FRM=146 should result in 
CONNECT and then later NO CARRIER, or +FCERROR... or even possibly 
ERROR.  OK doesn't mean anything, really, except that it "failed to 
properly detect the high-speed data carrier".

Get with your modem manufacturer and find out what the modem is doing at 
that point.  If they can tell you a workaround, then let us know, and we 
can do something.  Otherwise, they'll need to fix the firmware.
