My arduino uno seems to have a dead usb to serial chip. I was wondering if I could use the RX/TX pins to program it using a serial port on my computer? Any advice would be greatly appreciated.

You would need an RS232-to-TTL Serial conversion chip to do the level shifting.
OR
You can get an FTDI USB-to-TTL Serial cable for about $20.

Or you could use one of these cheap USB/Serial converters:

Thanks, I found schematics for the rs232 to TTL conversion, and I have all the parts lying around, so I think I will just make one.
