The maximum number of SPEED SEND/RECEIVE calls that can be used simultaneously
(FC53, FC63) depends only on the CPU (see above).
2.4 Characteristics of open TCP/IP communication
Open TCP/IP communication provides a program interface for the transfer of connection-
oriented and connectionless services. The establishment and termination of connections is
initiated here only via the "dynamic" program interface.
The CP supports communication via ISO-on-TCP connections for this interface.
