Hi Mohamed, you have too many solutions for this issue, some of they are:

1- Use a FTDI chip, I don't remember the part numbers but is something like FT232. Search google.
2- Use another PIC, as the PIC18F4550. This pic is similar in pinout to 877A, but richer in features. Also there is a USB stack from Microchip, FREE, and also from many others, just google it.
3- There are too many solutions, search in google for PIC with USB interface or other chip options.

I hope this help you. Best regards. Yosmany325

You can buy a cheap USB to serial TTL converter from Hong Kong for less than £2.00 on eBay from many suppliers all made up and ready to go. They don't come with driver software so you have to find it from the manufacture of the chip web site. The main problem with these devices is if you plug it into a different USB port the serial port number changes. Apart from that they are a fantastic buy.
