TFTP Does Not Respond with Port Unreachable

SUMMARY

If you attempt to TFTP to an IP address to a computer that does not have a TFTP server, the command prompt window appears to stop responding (hang); you can close the window, but the application doesn't time-out.

TFTP does not respond when a port is unreachable. TFTP waits indefinitely for a connection. In the case when the remote host does not have TFTP, an error message does not appear.
