TFTP Component

Properties   Methods   Events   Configuration Settings   Errors  

The TFTPClient component is used to exchange files with TFTP servers via the TFTP protocol defined in RFC 783.

Syntax

nsoftware.IPWorks.Tftp

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.
