For example, using the AGirs/Infrared4Arduino firmware for the Arduino, 
https://github.com/bengtmartensson/AGirs you can have it recognize 
either some protocols with parameters "transmit nec1 122 29" or or using 
named commands like "named my_device  my_command". In the latter case, 
the named commands have to be configured in. Not that IrScrutinizer can 
generate Arduino code automatically. (Export, select export format 
Arduino/Infrared4Arduino.)

At most for testing. You will have to write some "communication module" 
for bidirectional communication, call it terminal program if you wish.

Please also have a look at JGirs, 
https://github.com/bengtmartensson/JGirs which basically can 
functionally replace lircd.

Much to learn still you have, young padowan ;-).
