applying a modem init string (at+crm=150) in osxTiger

[zumzum]

My friend has bought a macbook and wants to use his Cdma1x phone as a modem.
In Windows he had to add an init string:

at+crm=150

to get it connected.

My phone doesn't need such a string in windows or in macos so I guess for my friends phone it is necessary to add the string also in macos.

I failed by adding a line in the modem script. I have added "write "at+crm=150"" but then the modem doesn't show any response.

I am using the modem script "au cdmaOne Bluetooth Adapter". I am using this script also for my other CDMA phone (Audiovox) - even though it is not connected via Bluetooth. Audiovox doesn't need any init string but this new phone needs, regardless of the operating system, to add "at+crm=150" to activate a 1x RTT packet switched call. Without this it just disconnects immediately after authentication.
I have tried already to write a terminal script (incl. creating a new folder in "library", containing that string and adding it in the ppp settings but I had no success, means no effect.

I also modified that "au cdmaOne Bluetooth Adapter" script by just adding "write "at+crm=150"" as follows:

.

.
@LABEL 3
matchclr
matchstr 1 13 "OK\13\10"
matchstr 2 101 "ERROR\13\10"
write "AT&F0E0Q0V1X4S0=0\13"
write "at+crm=150"
matchread 50
inctries
iftries 3 101
.
.
.
But the effect was that the modem didn't respond at all.

At the Apple Store nobody can help.

Thanx,
