# Setup connection
$IP = [System.Net.Dns]::GetHostAddresses($EndPoint)
$Address = [System.Net.IPAddress]::Parse($IP)
$Socket = New-Object System.Net.Sockets.TCPClient($Address,$Port)
# Setup stream wrtier
$Stream = $Socket.GetStream()
$Writer = New-Object System.IO.StreamWriter($Stream)
# Write message to stream

Enviar un mensaje con:
Send-TCPMessage -Port 29800 -Endpoint 192.168.0.1 -message "My first TCP message !"
Nota : los mensajes TCP pueden estar bloqueados por el firewall de su software o por cualquier firewall externo que esté tratando de atravesar. Asegúrese de que el puerto TCP que configuró en el comando anterior esté abierto y que haya configurado el servicio de escucha en el mismo puerto.
