serial communiction through PICf452..ISIS simulation

hello,

i had developed a code and the schematic for serial communication through pic18f452 ...using max 232...and rs232 cable...I have used PROTEUS ISIS to simulate the circuit....the code below will work when the either one of the two cases goes true....and and it is working but the problem i am facing is that in simulation when I execute the program and load the hex file in the controller in simulation its not working on the keys i defined for clockwise and ant- clockwise direction but it is moving clockwise when i press '2' and anti clockwise when i press '6'......and also if i change the characters for input they are not working for them......only '2',and '6' are working through numeric keypad....while between execution in ISIS the vitual terminal is also not showing the characters or any junk value.......I hope i defined my problem in suitable manner....please help...am in a great great trouble.........

bestregards

Dear Ali;
This is irshad Baig from Karachi . I m glad to hear you also from KHI. Can you tell me on my cell no what problem you are facing in serial of PIC. my cell no is 03218271102

Dear Sir;

Thank you sir for your consideration...but i came across a solution of this problem....and that is , I dont have to use max232 in PROTEUS SIMULATION......
