Not really sure, but figured it was worth a shot.

A few weeks ago, I was testing various ideas to get binary file transfers to
work while using Mystic as a front-end.  Here are the things I discovered:

1)  Text file transfers work fine.
2)  Binary transfers don't work (ZIP, etc).

I tried to add this to the WWIV source code to try and force telnet into binary
mode before the transfer:

outcomch('\xFF');
outcomch('\xFB');
outcomch('\x0');


Also tried this:

     outcomch((char)255);
     outcomch((char)251);
     outcomch((char)0);
     wait1(100);

Neither had an effect, unfortunately.  Basically what needs to happen is to
have the telnet session in binary mode from the start.  Transfers will work
fine if that was the case based on what I have been reading and investigating.
