My advice is:
Make backup's of your original WB disks.
The Serial Preferences is on the Extras disk, then on the prefs:
Baud Rate: 19200
Input Buffer Size: 4096
Handshaking: RTS/CTS
(the last ones leave it has it is)
Then save it, so the next time you boot from the wb disk, you don't have to do this again.
Then, follow Amiga Explorer instructions on how to transfer the needed files for Ae run on the amiga.~ :-D
