.EQU delay17 = $68		//$68 ought to give baud rate of 1200	//this worked way down to delay17=$40 ,delay18=$01. but a bit fast
.EQU delay18 = $01		//Probs with $01 $02 OK but a bit jumpy $08 OK $10 OK$20 OK$40 0k $80 OK$f0 OK; Not too much different from $0 for timing. Start of with dec.
.EQU delay19 = 1		;delay constants that can change serial rate etc. 0,0,9 gives about 1second at 1.6MHz
; a "3" in delay 19 gave Arduino count for "wait3" of about 24000. Now 24K * 1024 about 24Million. ie about 1.5 seconds at 16MHz
