Do you mean from inside or outside the phone. If outside you can enable the modem port for IR, serial cable or USB. using the modem link app in accessories. However you will find that this is only a FCLASS modem and doesn't support GSM features like sending SMS.

Internally there is a virtual com port between the WinCE os and the GSM modem but this is undocumented and you cannot open it under normal conditions as the OS has already opened the port for its own purposes.

That leaves you (and me) having to rely on the TAPI interface for accessing the modem features.
