TCP Driver write back documentation

I found two pages of documentation that seem to conflict with regard to the TCP driver write back capability.

says the TCP driver can write back to the connected port.

says that both UDP and TCP drivers are strictly passive listeners.

Is one of these out of date?

One of those is a little out of date or misleading.

The TCP driver also exposes a tag that, when written to, will write the data out over the TCP connection.
