Testing TXB Units

This is a collection of Methods and Tekniques for testing Translator Boards (TXB)

Notes
  1. Most of the communications line dumps in this document were made with software from "Frontline Test Systems" (fte.com). Frontline Test Systems has a prduct named Breakout that did almost all of the capture work. (Currently, 2024, it seams that the old Frontline Test Systems has stopped working with serial data acquision products.)

  2. Most of the Oscilloscope picture in this document were made using a Tektronix model TDS220 with a screen capture board that generated Post Script images.

  3. Analysis software used in determining protocol interactions were written in flex and C. The output of flex was compiled into C and then made an execuitable file.

  4. The compute environment for most protocol evaluation was MS-DOS running under Windows XP with the enhancement package DJGPP that provided an almost Linux type keyboard system.

  5. All source files are kept in a Revision Control System (RCS) directory.

  6. Most of the results of processing are typeset using the LaTeX documentions system.

  7. Source code for MakeSecs, and other locally developed analysis software is not available.
