title  "PACDTMF.asm - DTMF Relay Packet board."
;
;  This Program receives DTMF commands and outputs cw id tones
;    4 relays (or optional stuff) can be closed 
;    Relays are 1-5 with 5 being a dummy
;	CWID is a morse code of a call sign plus a packet w/ positon
;	  if available.
; The commands are:
; 5 = CWID and dummy relay 
; 6 = close relay # + CWID 
; 7 = open  relay # + CWID 
; 8 = pulse relay # + CWID 
; 9 = hold relay # while key is pressed + CWID 
; 0 = 20 sec relay # +CWID
; dtmfA = 10 sec tone + CWID
; dtmfB = 10 sec radio key + CWID 
; 
; Options include:
;   commands 6-9 xmit a morse 'K' instead of full CWID (for speed)
;   One or more precursor access characters for each command
;   Relays are only capable of conducting 1 A nominally. so NFETs 
;     can be substituded for relays 2 and 4 ( 3 is lost)
;   Relays 2 and 4 can also be replaced with Hobby servo outputs.
