1-31 TTY lines (TCP ports mapped from 2001 or 6001 depends binary or ascii mode to 2032 or 6032) 33 aux. 33 - rest used for VTY access. It looks that your platform supports a 4 port asynch card anyway. If that you telnet to 2005 or 6005 than this will be a reverse telnet connection to your aux port.

Erlang gen_tcp:recv(Socket, Length) semantics - itgo.me

In my last few articles about Erlang we've covered the basics of network programming with gen_tcp and Erlang/OTP's gen_server, or generic server, module.Let's combine the two. In most people's minds "server" means network server, but Erlang uses the terminology in the most abstract sense.

This option appears to be VERY Linux specific, and its existence in future Linux kernel versions is also worrying since the option is part of RFC 2292 which is since long (2003) obsoleted by RFC 3542 that explicitly removes this possibility to get packet information from a stream socket. For comparision: it has existed in FreeBSD but is now removed, at least since FreeBSD 10.

If the packet option is set then gen_tcp will automatically append/strip that many bytes from the package. If you specify packet 0 then you must do a recv/2 with a length >= 0 and the behaviour is the same as in C. You can simulate non
