Well, the original question was about listening ports.

sockinfo with option C shows "call" or listening ports/sockets.
Those waiting for an incoming connection.


showconn, as James points out, shows a nice list of connected ports.

sockinfo with the G option, shows processes that have or had
sockets open. But you must select the process (P command) to see
the sockets for that process.

No nice list of all sockets in use.

Example, my DSDAD process (started with NSCONTROL START; no job or
session with it) looks like this after specifying my pin 41.

PROCESS DISPLAY  Pin=41   Lsi=$180.000003a0  Dest=0 ($.00000000)       3:52 pm

Here is WTRSH with a Whisper IDE connection, as well as listening ports.

ps: once on a process screen (P command), use the S command to see socket
specific details.
