The Synchronous Link Control Procedure is designed to control the interchange of messages on a point-to-point link between two TPF systems or between a TPF system and any other automatic system. The hardware characteristics of the link are as follows:
seven-bit character - b7 b6 b5 b4 b3 b2 b1
IBM eight-bit - 0 1 2 3 4 5 6 7
Thus, IBM eight-bit byte X'1F' will be represented as 1/15 in the seven-bit character code. The seven-bit code will be used throughout this document.
