He can transfer the file between the PC and the Amiga
using a Null Modem. Its really fairly easy.
Just run a Dos Term prg. on the PC and a Term prg. on
the Amiga. I used JR Com on my A500 and TelTerm on the PC.
Worked great. Should still be able to buy a Null Modem
at Radio Shack for just a few bucks ($5 to $10).
