how home auto circuit designed in proteus communicate with HASERVER

hello froends ,
i have designed the home automation project in proteus professional . then i i upload the sourcecode ha.c and debug then the com port is glowing . but my doubt is how to communicate with "haserver"  should i have to change port no or any changes ???

2 . now is it nesessary to use relay circuit at the appliance section for viewing the status or only interfacing the led with uln2003A ic (which is connected with mc) .
 plz clarify the doubts clearly !!!

Ans1: HAserver will not work with proteus!
Ans2: LEDs are helpful in debugging etc. so.. if you want you can keep them, otherwise you can connect ULN2003 directly to your controller and drive relay!
