Awesome, wow, I totally forgot 'minicom'...'sudo apt-get install minicom' :)
Ok, will do, was going exactly by the Wiki so maybe that was my mistake ;]
appreciate the help. I'll dig up the manual for the proper codes to send the
modem for API mode and bps.

Assuming that your modem is still configured at 9600bps, use a terminal
emulation program such as minicom, make sure it's set at the correct baud rate
and on the right tty.
Then issue '+++', wait for a second, then send your init string.
You can refer to the maxstream manuel to make sure you have the correct init
I had a quick look and I think the init string you listed would be more
appropriate for a 9Xtend module (it reduced the output power ATPL2) and it
doesn't put the module in API mode (ATAP1).
