[A] Stdin/stdout, spawning a thread (threaded version).
Like `-`, but forces threaded mode instead of async mode
Use when standard input is not `epoll(7)`-able or you want to avoid setting it to nonblocking mode.

Read input from console, print to console. Uses threaded implementation even on UNIX unless requested by `--async-stdio` CLI option.
Typically this specifier can be specified only one time.
Example: simulate `cat(1)`. This is an exception from "only one time" rule above:
websocat - -
Example: SSH transport
ssh -c ProxyCommand='websocat - ws://myserver/mywebsocket' user@myserver
