+; 0.8 Some text commands implemented, only static text for now though\r
; 0.7 Debug Serial TX in ISR now, checksum check for incoming packets in place, A/D works, solved the master reset prob\r
; (by calling the INT handler from TMR2 ISR code (too much interrupt latency when transmitting)\r
; 0.6 Some more LCD info and clean-up of the Unilink recovery code, some problems with master resetting :(\r
