Start a 5250 terminal emulator session, and then log on to the target OS/400.
Verify the IBMRDB mode description with the DSPMODD command. The default mode name for APPC/DRDA conversations is IBMRDB; it is predefined on all OS/400 machines.
Verify that the mode name exists.
Note the parameters for maximum sessions, maximum conversations, locally controlled sessions, and inbound/outbound pacing values.
