You can use Proterm 3.0 on an Apple II and use any of these protocols x modem, x modem-CRC, x modem-1K, x modem-4k, Y modem, Y modem G, Y modem 4K, z modem and KERMIT. Proterm 3.0 is from INSYNC software and is about $79. It is a very good piece of software and well worth the price in my estimation. Good luck, Tom Barner TBarner@RCN.mass.edu
