NAME
       tcp-environ - TCP-related environment variables

DESCRIPTION
       The  following environment variables describe a TCP connection.	They are set up by tcp-env, tcpclient, and tcpserver.  Note that TCPLOCAL-
       HOST, TCPREMOTEHOST, and TCPREMOTEINFO can contain arbitrary characters.

       PROTO
	    The string TCP.

       TCPLOCALHOST
	    The domain name of the local host, with uppercase letters converted to lowercase.  If there is no currently available domain name  for
	    the local IP address, TCPLOCALHOST is not set.

       TCPLOCALIP
	    The IP address of the local host, in dotted-decimal form.

       TCPLOCALPORT
	    The local TCP port number, in decimal.

       TCPREMOTEHOST
	    The domain name of the remote host, with uppercase letters converted to lowercase.	If there is no currently available domain name for
	    the remote IP address, TCPREMOTEHOST is not set.

       TCPREMOTEINFO
	    A connection-specific string, perhaps a username, supplied by the remote host via 931/1413/IDENT/TAP.  If the remote host did not sup-
	    ply connection information, TCPREMOTEINFO is not set.

       TCPREMOTEIP
	    The IP address of the remote host.

       TCPREMOTEPORT
	    The remote TCP port number.
