probably your controller's frequency is not correct then. In proteus simulator does not take account of external crystal. click on 8051 in schematic go to properties and change crystal frequency to 11.0592Mhz and try again.

Hi...i am a new user here. I was also facing the same issue so according to my solution you should remove max232 from proteus and connect RXD of controller to RXD of COMPIM and Txd of controller to TXD of COMPIM directly.
