Patton) Newsgroups: comp.dcom.telecom Subject: Character Codes Message-ID:Date: 25 Sep 89 23:47:25 GMT Sender: news@vector.Dallas.TX.US Lines: 15 Approved: telecom-request@vector.dallas.tx.us X-Submissions-To: telecom@eecs.nwu.edu X-Administrivia-To: telecom-request@vector.dallas.tx.us X-TELECOM-Digest: volume 9, issue 408, message 4 of 9 For fuller details on CCITT #2 and other codes, I refer to Appendix C of "Technical Aspects of Data Communication" by John E. McNamara (who is a reader of this group). This appendix lists 12 different 5-level codes as well as 2 6-level codes and the "standard" 7-level code. The order seems to differ from what you list (but that's probably because the bits are backwards :-). It also points out that BEL wasn't always FIGS-J, there were also codes where it was FIGS-S. I'll bet this was a barrel of laughs if you hooked up a machine with the wrong code! In addition, for those discussing transmission rates, Appendix E of that same book lists many speed/format combinations and what use they were put to. The chart in this appendix lists 12 different combinations of baud rate and stop bits for 5-level codes. -Mike Patton
