Send a String over a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.SendString, which encodes a string using StringCharset and sends the resulting bytes over the connected socket. No delimiter, terminator, or length prefix is added.

#  connection succeeds; the 4th is the maximum time to wait, in milliseconds.

#  Encode the string using StringCharset and send the resulting bytes.  No delimiter, terminator, or
