Using FastLynx 3.3 to Transfer Files To/From Old/Modern PCs

By 'modern PC', I am referring to a PC that is modern enough to run say, Windows 2000.
By 'old PC', I am referring to either an 8088 or 80286 or 80386 or 80486 based PC, running DOS.

FastLynx 3.3 is a modern commercial product that is capable of file transfers, via serial or parallel cable, between an 'old' PC running DOS and a 'modern' PC.

The cables required are the same ones used for Laplink and INTERSVR/INTERLNK.

Method 1:  Via serial cable

Method 2:  Via parallel cable
