So the modem got removed after the 3 AT command timeouts, that's good 
news at least. The reason for the modem getting disconnected and not 
responding, though, is not that good news. At least you should have been 
able to recover the modem launching a re-scan, as ttyS1 should have been 
released after having the modem removed.
