NAME
     tcp-environ - TCP-related environment variables

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

     PROTO
          The string TCP.

     TCPLOCALHOST
          The domain name of the local host, with uppercase  let-
          ters  converted to lowercase.  If there is no currently
          available domain name for the local IP address,  TCPLO-
          CALHOST 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 let-
          ters  converted to lowercase.  If there is no currently
          available domain name for the remote IP address, TCPRE-
          MOTEHOST is not set.

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

     TCPREMOTEIP
          The IP address of the remote host.

     TCPREMOTEPORT
          The remote TCP port number.
