Null modem cables are
Very slow, slower then floppy drive, why torturing yourself?
I agree. Null modem cables are crap slow for file transfers.
If I wanted to network my PC and Amiga together cheaply I would just use a PARnet cable which I have had since 1980s. If u lost urs then you can buy a new one. PARnet is something like 8x faster than serial cable. It is quite useable.
I would recommend either the CF Card transfer method or the PARnet method.
You are supposed to use your serial port to run a NULL modem cable from your A600 to your
other A600 so you can play Stunt Car Racer in head to head 2 player mode, or Lotus Turbo Espirit in 2,3 or 4 player mode.
