@ jcwh
if ur checking it on real hardware with wire then the supplies of both circuits should be common
ground should be common for wired commuincation
@ jcwh
before going to wireless u should check it with wire link
once it work with wire it means ur code is ok
then u will be sure that code is ok now problem is in the wireless link
ru using ordinary RF 434 MHz module
it has bad accuracy if u directly connect it with controller
by using decoder...
@ jcwh
how u try this
generate a 2400bps and then connect it with pc
often people do mistake in connections with pc
u has to use max232 and follow this sequence of connections

after opening the link click on description

reading function is ok u write
if problem not solved u can write asm code in c function and also c code is given in its data sheet
anyhow
And don't forget to set these fuses:
Brown-out detection level at VCC=2.7 V
Brown-out detection enabled
or your eeprom may get corrupted during power on/off
yes lloydi12345
it is possible
just u has to use if else statements
when u receive a character compare if it is 'A' then a specific pattern of led on on port
if it is 'B' then another sequence sent to port
