//This is a main procedure of PairPhone testing software
//one-thread implementation as a infinite loop contained procedures for:
//-receiving baseband, demodulating, decrypting, decompressing, playing over earphones (RX)
//-recording voice from mike, compressing, encrypting, modulating, sending baseband into line (TX)
//-scan keyboard, processing. Suspending thread if no job (CTR)
