HOW TO USE MACROS?
In macros you can use all characters from keyboard and any ASCII char if 
you use $xx or #xxx. Where $xx is hex and #xxx dec format of ascii code. 
If you want to use # or $ char in macro you should type it twice ($$=$ and 
##=#).
To calculate XOR checksum byte use %XOR command.
To calculate SUM (1byte sum) checksum byte use %SUM command.
To insert delay in macro string use %DLYxxxx, where xxxx is value 0000-
9999 in ms.

Macro examples...

example 1.
abcdefgh123456 - this will send 'abcdefgh123456'

example 2.
AT#013#010 - this will send AT and "CR" + "LF" (cariage return + line 
feed)

example 3.
X1##Y2##Z3##$0D$0A - this will send 'X1#Y2#Z3#"CR""LF"'

example 4.
$$value=123$0D - this will send '$value=123"CR"'

example 5.
$01$02$03$04$05%XOR - this will send $01 $02 $03 $04 $05 and 
calculated 
XOR byte $01 

example 6.
ABC%DLY0123DEF - this will send ABC and after ~123ms DEF

example 7.
$01$02$03%SUM - this will send $01$02$03$06

Macro string can be up to 128 characters long.
