Hi,

Rather than parsing the whole data I am now emulating terminal like interpretation right into the ISR, with inbuilt two digit decimal ASCII to binary conversion. This involves getting the terminal co-ordinate data and assigning the real text data into pre-defined arrays rather than one single ring bufffer. I am unsure about my practices with the indirecting file addresing in the asm. Any tutorial or tips on the same would be appreciated. Also please let me know if bank switching in asm ISR is okay. Anyway the FSR values are restored with the Retfie FAST. I am not using any calls within the ISR, rather Goto. I believe this would not modify the shadow registers(only one level deep).

Wish me luck I need it.
