hey dude even i have the same problem .
. i need to connect my 6610 to pc com port .. and i get no response with AT commands.. i wonder why no one is replying to u or me . if u do know whats the problem please let me know
Q: Can I send AT commands to the device?
A: Yes, but the Connection Manager and the tray icon must not run, because both use the Phone API, which will block the serial port and you can not connect directly.
