If you want a quick and easy way to transfer files to/from your Amiga (or any other computer you might have the WiModem232 plugged into) to/from your PC, grab WiBridge:
http://home.reidspace.com/index.php?id=c64-stuff
Run this program on your PC. It will show you the IP address of the portal to your PC. Run a terminal program on your Amiga and type:
ATDT192.168.xxx.yyy:6464 (and press ENTER)
Where xxx and yyy are the last two values in the IP address shown when running the WiBridge program.
You will see CONNECT and then some text. You have complete access to your PC's filesystem to browse files. You can upload/download files via Zmodem or Xmodem by using the WiBridge's pull-down menu.
I was able to run 57600 baud with JR-Comm and 115200 baud with NComm and BaudBandit.device. I was getting around 10200 CPS. We would have killed for that speed back in the day! LOL!
