Problem with UART Core

I made a driver for the UART core to talk to my computer via RS-232 on a DE2-115 dev board. Im using the NIOS.

It works great sending data to hyperterminal, however receiving data is strange.

I wont get any data for the first 20 characters or so, then I get a character, then another 10 go by without getting them, THEN ...after this it somehow syncs up and receives every character after that perfectly.

Any ideas what could be wrong with this based upon the clues I have given?

    Best to use something other than hyperterminal - it behaves strangely.

    Try using 'putty' - tends to work much better.

    Yes I agree using PuTTY works better! Furthermore hyperterminal is no longer supported in windows 7.
