Downloading problems with WiModem 232 and a UDS-10

I was not able to download a binary file with Zmodem at 9600 baud though, so if you can put that TESTFILE that I uploaded in one of your download directories I would like to try to download it at 9600 to see if that works with various protocols.  Zmodem is super touchy, so I was surprised to see the upload work.  I uploaded it also with YModem-1K and that worked fine.  The Xmodem and Ymodem protocols don't have tiny timing windows... they still have windows, but typically it's not an issue for WiFi<>router connections.  In your case you have a Serial<>Ethernet<>router connection.  I did see that the UDS-10 is not fully asynchronous (why it has the collision LED).  Its certainly possible that the timing at higher baud rates is too fast and collisions are occurring.

Okay. I put the TESTFILE in File Sig 3.

19200 baud is as fast as the Atari Mega ST4 can achieve stock.

Thanks.
