Editing FidoNet (section)

===Technical specifications===
FidoNet contained several technical specifications for compatibility between systems.  The most basic of all is ''FTS-0001'',<ref>{{cite web |url=http://ftsc.org/docs/fts-0001.016 |title=FTS-0001 |first=Randy|last=Bush |date=1995-09-30 |format=TXT |website=FidoNet Technical Standards Committee |url-status=live |archive-url=https://web.archive.org/web/20080530024932/http://ftsc.org/docs/fts-0001.016 |archive-date=2008-05-30 }}</ref> with which all FidoNet systems are required to comply as a minimum requirement.  FTS-0001 defined:
*Handshaking - the protocols used by mailer software to identify each other and exchange meta-information about the session.
*Transfer protocol ''([[XMODEM]])'' - the protocols to be used for transferring files containing FidoNet mail between systems.
*Message format - the standard format for FidoNet messages during the time which they were exchanged between systems.

Other specifications that were commonly used provided for ''echomail'', different transfer protocols and handshake methods (''e.g.: Yoohoo/Yoohoo2u2, EMSI''), file compression, nodelist format, transfer over reliable connections such as the Internet ([[Binkp]]), and other aspects.
