Does the modem expose a network device port?  Can you send along the
lsusb -v output for it?  If so, we should first try to use the network
port instead.  If you can get the response, what does the modem say when
you send it:

AT^GETPORTMODE

Second, it might be worth modifying the Huawei plugin to send &D1 along
with the X4 &C1 just to see if the modem actually bothers to update the
serial port control signals, which could be causing the hangup.
