I was attempting to run a old style BBS via DOSBox. I have tried multiple BBS and all have the same issue when older computers are calling into it (old 8 bit computers like ATARI, TI, Commodore, etc.)

It seems that when the older computers accessing the BBS via DOSBox the BBS is receiving double characters. I have tried the older computer going directly to a newer BBS like Mystic or Syncronet on the same computer and the older systems do not do this, so this leads me to beleive it is an issue with DosBox and older systems or even maybe somehting being interpreted via DosBox and the older BBS software. The same BBS software running on an older machine via actual MSDOS does not behave this way..

Is there a setting somewhere that I need to change or is this by design within DOSBox?
