Function
The SktTCPAccept instruction requests accepting the port specified with the local TCP port number
ScrTcpPort. To do this, it executes the Socket(), Bind(), Listen(), and Accept() socket functions. The
instruction waits for the time set with timeout time TimeOut for a connection to be established with the
remote node. The connection is established when the instruction is completed normally (i.e., when the
value of Done changes to TRUE).
