FTSC-0006 ~ YooHoo and YooHoo/2u2

[ONiX]

The YOOHOO protocol was designed to automate the initial connection between two Bulletin Board Systems (BBS). When one system dials another, YOOHOO allows them to electronically "introduce" themselves, verifying their FidoNet addresses and determining which file transfer protocols (like XMODEM, YMODEM, or ZMODEM) both systems support.
