VZW TP USB DUN using WModem

[bako]

Hi ppls.
I unlocked VZW TP and use it in another country CDMA network. I prefer MightyROM. Internet Sharing (ICS) works good. But when i use WModem i have such problem:
I succsesfully can connect to phone via USB Serial Port, but phone always say "OK" on my commands.
I tried to use different software: minicom and cu in Linux, Hyper Terminal in Windoze, but always got "OK". I tried to play with "Mobile IP"(M.IP) variables in ##778#, but fail... I tried to use Verizon shiped ROMs and different kitchens, but always fails
Example:
I attaching to Serial Port and enter:
ATZ
its respond
OK
now i want to call Access Server (AS) by using ATDT. I am entering:
ATDT#777
modem must do a try to call AS, but its doing nothing. I expect "CONNECT" but
this shit say me OK. At this plase OK is unexpectable respond!!!
Well. I trying to ask Modem Info by ATI, ATI1, ATI2, etc
modem say me OK... Its unlogical for me...
I am trying to use Sprint radio but got the same results
Also i tried Init String, like ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Nothin helps On any command phone say me "OK"
Q: Anybody solved such problem in VZW TP or everybody use ICS an have fun? Does anybody got something else than "OK" ?
