====== FidoNet Extensions ======

===== Control Paragraphs =====
FidoNet [[http://ftsc.org/docs/fts-4000.001|control paragraphs]] (a.k.a. "kludge lines") are how extensible message metadata is shared among FidoNet nodes.

Synchronet and [[util:SBBSecho]] have extended FidoNet messages with the following control paragraphs:

^ Control Tag     ^ Description ^
| FORMAT: //fmt// | Indicate if the message text was pre-formatted (''FORMAT: fixed'') or intended to be line/word-wrapped when viewed, potentially with [[markup]] codes parsed and applied to the output (''FORMAT: flowed'', the default) |
| COLS: //n//     | Specified width (positive decimal number, in columns) of message author's editor or terminal; potentially useful when re-flowing/wrapping message text for display |
| BBSID: //id//   | QWK BBS ID (1-8 alphanumeric characters) of originating BBS, when applicable; for routed QWKnet messages, the BBS ID may be prepended with slash-separated hop-IDs (e.g. "//hub-id/////bbs-id//") |\
| NOTE: //info//  | Message text editor name and version information (not originated by Synchronet/SBBSecho) |
