Sometimes, you may notice that even if you do not run the command IT_MacTCPInit, you can still use the TCP commands of 4D Internet Commands. So, you might be wondering if that command is still needed.

The answer is Yes, you still need to initialize the TCP layer using IT_MacTCPInit. The only reason why it would work without using that command is if another application already initialized the TCP layer. It may occasionally work but it is not a reliable option.
