RS-232 is an electrical standard specifing a connector and voltage levels. It says nothing about ASCII or anything else about the data being transmitted. Some RS-232 terminals were far more sophisticated than rxvt. Not only did they support the same ANSI command set that rxvt supports, but some also supported sophisticated vector graphics command sets, printing to attached printers, and various other things that rxvt has never dreamed of. -- Grant
