I have included a working DUAL UART program. I tried my best to get the sircs to work, but was unable to do so. One way to resolve the problem, I think, is to increase the amount of variables from 17 to maybe 48, or some number along those lines. For the SX52, there seems to be something weird going on when you start to implement 'bank' arrays. In all fairness, the code does implement the serial 'bank' array, and the DUAL UART works. It is when you add the sircs code that the problem shows up.
 

It was mentioned that there might be some problem with the sircs asm code, so the code listing below reflects the use of non asm sircs code. I just wanted to see if it really was the sircs asm code that was the problem. This code does not work either. So, the conclusion is, on an SX52 chip, if you mix uart with some sircs code neither one works. I do not have enough variable space to try a non serial 'bank' situation.

 

I am also looking for a UART asm program thats works on an SX52 chip. I tried the example in Gunther's book, but could not get that to work. The example in the download area does not work either. I have not tried the Al Williams example just yet, but I think that will not work either. I have run his UART example on an SX28, and it worked.

 

Thanks Sparks and Jon for the help.
