Displaying channel status

To display the status of a channel or a set of channels using the MQSC commands, use DISPLAY CHSTATUS.

where nnn is the number of active connections, and status is one of the following:

To display more information about the channel status, press the Status key (F11) on the List Channel or the Display, or Alter channel panels to display the List Channels - Current Status panel (see Figure 1).
