Hi,we are doing the same project(LED scrolling display using 8051)except the use of comp port,instead of that we are using GSM modem to receive the display message.we are using (7-rows,48-column ->LED matrix display)for display,AT89S52 microcontroller,GSm(sim 900) for reception of the message from a mobile phone.can u give the complete schematic of the project and code for interfacing microcontroller with GSM and LED display matrix?

The hardware for connecting to a PC or a modem is virtually , if not exactly, the same. Just check the voltage levels.
The software will be more complicated.
I suggest you build the hardware as it is, to talk to a PC.
When you have it working, look as other projects ( some on here) that talk to a GSM modem.
Finally adapt the code for your project.
