Great that you tried it this way !

115200 8N1 is OK, however you should receive mainly ASCII
data. When the modem powers up, it could be that you receive
a few binary data from the bootloader, but after that its 
mainly ASCII. If the GSM modem has started, but GSM has not 
been turned on, you should receive something like that, one 
line every few second:

IQ EXT: ADC End      ADC :407 0
IQ EXT: ADC End      ADC :509 0

If the modem is idle and registered to a network, it looks like this:

IQ EXT: ADC EndNP_I  15320 0 308 149 1327 214 3 3 3 3

Please be sure not to send anything to the modem, this might
disturb the firmware.
