To transmit a carrier-wave signal, use the sl_Send API with NULL buffer and 0 (zero) length.
Use the flags parameter in the sl_Send API to signal the tone offset (-25 to 25).
Stopping CW transmission is done by triggering another sl_Send API with flags = 128 (decimal) as follows: sl_Send (soc,NULL,0,128);
