Wimodem 232 errors when transferring files

I don't have one of these, but my guess would be flow control issues or insufficient buffering.
With this device can you change and try different baud rates to see if that has an effect?

I read through the use manual and in the "Advanced Configuration" section of the manual, it mentions having to solder jumpers between some pads to enable hardware flow control.

I found the manual here http://biosrhythm.com/wifi232/WiFi232ModemUsersGuide.pdf

One other thing that just occurred to me is that the reliability of the connection could depend on which Amiga you are using. I seem to remember struggling to get high baud rates with the A1000 & A2000. You might find that you need to use some other serial device. I remember using one called baud bandit that worked well. Not sure but might be on Aminet or others.
