You are incorrect. The phone is still enabled, it still receives SMS and can use GPRS. Programs like KSE TrueFax can use it to make calls/send faxes. You only cannot receive/make calls manually. To kill cprog and prevent it from running you should register VK_HANGUP and VK_ANSWER hotkeys. Here are their defines:
#define VK_HANGUP 0x73 // VK_F4
#define VK_ANSWER 0x72 // VK_F5
Look into KillApp.cpp from CryptoPhone source code for an example.
