Mike,

    I did try to use Telix on PC and ProTerm on Apple //c and Apple IIgs.  5 
pin to 25 pin cable for Apple //c does the same as 8 pin to 25 pin cable for 
Apple IIgs.  Zmodem is doing very well without any errors to transfer files 
from PC to Apple //c or IIgs.  It runs at 2400 baud and 9600 baud which it 
should work fine.  Sometimes, Xmodem and Ymodem may do OK, but Zmodem is 
better.
