Mac CDMA Modem Script help req

I am trying to connect an LG LSP 350r Fixed Wireless Phone, running a CDMA network (on Qualcomm CDMA MSM Chipt)

It connects from a Windows based machine.

From a Mac it repeatedly sends the 'No Carrier' signal
(i tried various Ross Barkman's scripts. The phone is obviously activated for internet service, since its connecting from a Windows machine. Upon connecting via USB, on my Mac it recognises the phone as Qualcomm CDMA Technologies MSM)
