block TCON must be called for each connection.
A separate connection must be established for each communications partner even if
identical blocks of data are being sent.
After a successful transfer of the data, a connection can be terminated. A connection is also
terminated by calling "TDISCON".

Connection abort
If an existing connection is aborted by the communications partner or due to disturbances on
the network, the connection must also be terminated by calling TDISCON. Make sure that
you take this into account in your programming.
