For UDP, the number of times the string is sent is equal to the number of packets sent. For TCP, the number of times the string is sent may (or may not) be equal to the number of packets sent, because TCP controls how data is packetized and sent out. Enter the following:  Protocol: Select the type of packet to send (TCP or UDP).  Hostname: Specify a host name or IPaddress of the host to send the packet to.  Port: Specify a TCP or UDP port number of the host to send the packet to.  String: Enter a set of up to 64 characters.
