both...

this is what i want to do.

from pc, i'll sent a txt file using hyper link. then, on my 16f877a side, it will auto recieve with it's uart capability. then, my controller will constantly scan the buffer. if there is something in the buffer, it will halt the program and start recieving the data.

the problem is that i dono how 2 enable that rs232 interupt, how 2 chk the buffer and how 2 read the buffer.
