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