Uart with embedded FIFO

Hey I've been looking through these forums and I see many have used the fifoed avalon uart to solve buffering problems.

I have implemented it into my system (uClinux OS, custom board, cyclone III) but I'm not getting any response from the uart.

Generated fine in SOPC; Compiled in Quartus

I'm using the fifoed uart to replace the regular altera uart; which works fine until the baudrate is too high for the system to keep up consistently.

My current understanding from I've read is that it should work without any software changes but for its not working at the moment.

I have messed around in an attempt to get this working so I have a few questions from it.

How important is the modification from the .pm file?

In the .ptf file the fifoed avalon uart comes up as a no legacy module is this correct?

Any help would be most appreciated.
