1: The PROT issue is indeed irrelevent, but a simple fix at least lets
you know if PROT is supported.
Something like this maybe, so long as ftpFeatProt is added to the set:
if Pos('PROT', Feat) = 1 then begin
if Feat = 'PROT' then
FSupportedExtensions := FSupportedExtensions +
[ftpFeatProt];
if Pos('C', Feat) > 5 then
FSupportedExtensions := FSupportedExtensions +
[ftpFeatProtC];
if (Pos('P', Feat) > 5) then
FSupportedExtensions := FSupportedExtensions +
[ftpFeatProtP];
2: This server requires Passive mode when using AuthTls, so another
step forward.
3: Now I have an interesting one and it's difficult to know from which
end the problem is being initiated.
I have 2 ftp components and both are logged into the server. The first
just does a LIST command every 3 seconds. The second does the GET commands.
After 198 GETs I receive and error 10054. I re-connect both ftp clients
and after a further 198 GETs the same thing happens again.
Error 10054 is a "connection reset by peer" message, which would imply
that it's the server that has initiated this. But is there anything at
the ftp client end that could cause the server to behave as it does?
If I log into the server with the SSL Mode set to sslTypeNone, this
problem does not occur.
Any clues much appreciated.

I would suggest you at least try the compiled version of my high level
TMagFtp component from:
https://www.magsys.co.uk/delphi/magxfer.asp
which handles all this stuff automatically. If TMagFtp works, then you
can look at the source to see why.
The one thing I have found is that when I execute the featAsync,
I do not see the PROT in the list of supported extensions. When I
look at the source code, you are looking for "PROT C" or "PROT
P". This server only returns "PROT".
This may be irrelevant, the feature list is designed to tell you which
commands you can use, they don't stop you using them anyway (probably,
not looked at the code in a while).
