### 17`` TCP Redirect: tcp^ via Channels

( require net/tcp-redirect)

The net/tcp-redirect library provides a function for directing some TCP port numbers to use buffered channels instead of the TCP support from scheme/tcp.

( tcp-redirect port-numbers) → unit?
port-numbers : ( listof ( integer-in 0 65535))

Returns a unit that implements tcp^. For port numbers not listed in port-numbers, the unit’s implementations are the scheme/tcp implementations.

For the port numbers listed in port-numbers and for connections to "127.0.0.1", the unit’s implementation does not use TCP connections, but instead uses internal buffered channels. Such channels behave exactly as TCP listeners and ports.
