Description
This command accepts incoming connections on a listening TCP socket. A new socket instance is cre-
ated for each accepted connection. The new socket is connected with the host and the response returns
its instance number.
NON-BLOCKING mode:
This command must be issued repeatedly (polled) for incoming connections. If no incoming
connection request exists, the module will respond with error code 0006h (EWOULDBLOCK).
BLOCKING mode:
This command will block until a connection request has been detected.
Note: This command will only be accepted if there is a free instance to use for accepted connections.
For blocking connections, this command will reserve an instance.
