PCZ - A Public Domain implementation of Zmodem, Xmodem, Xmodem-1K, Sealink, Ymodem for the IBM PC family PcConnect Zmodem by Drue Kennon and Gary Smith PCZ is a public domain Zmodem implemen tation that will allow users of commun ication software that does not implement internal Zmodem to access it through an external program. It is a fully-featured version of Zmodem, but does not have the professional and commercial polish of a program like Omen Tech's DSZ. However we do believe that it will be suitable for the average BBS hacker.
