And I propose the removal of this glossary item: Recommended Standard 232C (RS232C) A standard for communications between serial devices. which is rather odd and only used in the definition of RS232C. I have a contributed patch in hand which starts implementing the switch to hyphens in RS232 in the serialcomms chapter. I intend to remove the -C's and commit it in a few days (after mentor auth.) unless something discourages me. Reasoning: The most recent related standard is called by it's developer TIA-232-F, but since TIA is an association under the umbrella of the EIA, it probably should be called "EIA/TIA-232-F" which is how this helpful web page has the full form: http://www.interfacebus.com/Design_Connector_RS232.html I like the way that page has most references: EIA-232; it's sort of a lowest-common-denominator when you don't need to be more specific. But RS-232 will surely be more widely recognized for a long time. BTW, I have a book with excerpts of official EIA RS-232-C documents in which they used hyphens, as in RS-232-C and RS-422. I've been told that Google reports: RS232 3,950,000 results RS-232 7,240,000 results Interested readers can easily-enough find info on the many related (old, newer, newest, 25-pin, 9-pin, USA, ISO) standards outside FreeBSD documents.
