The following site has the data you would need to write a Function or Subroutine for EBCDIC to ASCII (or vice versa) conversion. http://czyborra.com/charsets/iso646.html
The code should be easy to write using a pair of arrays or using one code as subscript into an array containing corresponding values of the other code.
There are likely to be other sites. I used ASCII & EBCDIC as keywords to find the above site. A different or better search engine might have found other sites of interest.
Are you aware that there are various Terminal Emulation packages available? Procom Plus from QuarterDeck allows a PC to act like a Mainframe Terminal. Perhaps what you really want is a terminal emulator.
I think QuarterDeck was bought out by somebody (Maybe Symantec).
