Configuration Settings
The TFTPClient component is used to exchange files
with TFTP servers via the TFTP protocol defined in RFC 783.
NOTE: What follows is a very short description of the component interfaces.
For more information, please consult the help files that come with the respective package.
Remarks
To use the component, first specify the TFTPServer, then
a LocalFile and a RemoteFile, and then call GetFile
or PutFile. The
Transfer event shows the progress of the transfer.
Potential transmission errors and packet loss are managed by the
Timeout property which controls the maximum time to
wait for a response from the server, and the MaxRetransmits
property which specifies how many times to resend a failed
packet before giving up.
