Hello, I am working on a project using an 84 where I need to read a 10 bit code
 with a carrige return from a RS-232 port.  A small table of these 10 bit codes
 will be held in the EEPROM where the code read in will be matched to one in the
 table and an assigned  decimal or hex value returned.  This value is
 manipulated to drive a 4 digit 7 segement display network.  Meanwhile bells and
 whistles are going off and an analog storage chip sends voice to a
 speaker.-------
I already have the code written for the display , sirens, bells, and voice chip
 and it is working satisfactorily.  Now I need to figure out a way to interface
 with the RS-232 and a small read write table.  I would apreciate any pointers
 anyone may have, but please keep them in laymens terms as I am a beginer and
 know little about RS-232 pinout and functionality

  Thanks,  Dave
