KISS TCP only accepts one client

[elafargue]

It looks like multiple clients can connect to the KISS TCP port on direwolf, but only the first one that connects to it actually receives data, is that correct?

Previously only one TCP KISS client could be accommodated at a time.
The version in the "dev" branch (1.5 dev A or later) can handle multiple TCP KISS clients at the same time.
