Abstract
A method of sending self-clocking data characters and control characters in a sequence from a first communications node to a second node includes the steps of: encoding each data character as respective code pairs of the form 0XX . . . X1 and 1XX . . . X0 where the X's are the zero and one bits of the data character; encoding each control character as respective code pairs of the form 0XX . . . X0 and 1XX . . . X1 where again the X's are the zero and one bits of the control character; and transmitting, for each character in said sequence, the particular code in that character's code pair whose first code bit is the opposite of the last code bit of the immediately preceding character in the sequence.
