#176277 - this is NOT an ISR
Responding to: ???'s previous message
whatever you think and however you have coded it and even if it is activetd by an interrupt this is NOT an ISR.

you do NOT in an ISR make any jnb RI,$ and suchthat will screw up all processing.

                                          maybe not            01/01/70 00:00      
                                             ES1 is non-standard            01/01/70 00:00

      I have problem with serial port 1 on ds89c450 (www.maxim-ic            01/01/70 00:00      
         MUCH better description needed            01/01/70 00:00      
            not it is not language            01/01/70 00:00      
               Which register bank are you using?            01/01/70 00:00
