We will help with specific errors, but we can't "check your code"

Write code a bit at a time and test as you go.
As Ajay said,start by checking that you can read the pulses coming from the TV remote.

cmmand bits are not getting read from pic IC(i.e,'tx' pin no.25)..
how to read cmmands bit from PIC16F877A('tx' pin)...?

"Tx:MOVF TXREG,0
BSF STATUS,5
B:BTFSS PIR1,4
GOTO B
BCF PIR1,4
RETURN
END"

instead of Tx that you used in your code we replace this code....will it work....?

greater:cjne a,#0cH,next
mov a,#30h
acall tx
jnb ri,$
clr ri
mov a,sbuf
cjne a,#'m',keymode1
clr mode
ret

in this what does that "#m" indicate??

0 is sent to pc software when power button is pressed. Pc software then replies with what mode is currently set in software. If it's 'm' then mouse mode else keyboard mode.

I don't think timer is used in this project. Just usual loops for generating delays.
