-HaTTY is a reduced character set RTTY based protocol with forward error correction developed for use in HABing. Currently this is a theoretical idea. HaTTY-1 is a numeric only protocol using 4 bits, HaTTY-2 is a alphanumeric protocol using 6 bits.
+HaTTY is a reduced character set RTTY based protocol with forward error correction developed for use in HABing. Currently this is a theoretical idea. HaTTY uses 4 bits for common numerical data and extends to 8 bits for characters. Only the characters below are permitted and all letters are upper case only.
