Zmodem....???

I've looked, but can't find sz and rz (zmodem) on the 7.1 CDs. Is it included or where can I find it/them?! Thanks, Fred -- -- ----/ / _ Fred A. Miller ---/ / (_)__ __ ____ __ Systems Administrator --/ /__/ / _ \/ // /\ \/ / Cornell Univ. Press Services -/____/_/_//_/\_,_/ /_/\_\ fm@cupserv.org
