SEXYZ is a protocol driver, not a new protocol. SEXYZ just implements the standard X/Y/ZMODEM protocols, no different than DSZ, FDSZ, GSZ, sb/rb, etc. ZMODEM may not have been designed for use over Telnet, but it works just fine over Telnet (or Raw TCP, or SSH, or RLogin). Many of ZMODEM's features (error detection, windowing) are redundant with TCP, but it has some other convenient features (auto-start, resume) that YMODEM does not have, so its still preferred.
