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
          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,  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.
