lyron:
SoftwareSerial sSerial = SoftwareSerial( 36, txPin );
Do NOT try to access invalid pins. The Tiny Core (like the Arduino Core) DOES NOT VALIDATE PIN NUMBERS
The core you are using includes "Tiny Debug Serial". I strongly suggest using Tiny Debug Serial instead of SoftwareSerial. There are some details available here...
