150 meters at higher speeds. Consult an Ethernet cable manufac-
turer for a recommended cable for your configuration.
2. Verify your Ethernet hub. See your Ethernet hub manual.
Verifying the RealPort Process: AIX
1. Type the following:
lsdev -Cc nts
2. If the sa devices are not in an available state, type the following from
the AIX prompt:
mkdev -1 sa#
cfgmgr
where # is the number of the Digi Device.
Verifying the RealPort Process: HP-UX
1. Verify that RealPort is running on the HP-UX operating system by
entering:
ps ef| grep drp
If you see an entry for each Digi Device similar to the following, the
RealPort process is running.
root 2254 1 0 Dec 13 ? 0:03/sbin/drpd 1 199.86.0.1 root 2049 1 0
Dec 13 ? 0:01/sbin/drpd 1 199.86.5.1
2. If the daemon is not running, enter this command at a root prompt:
/usr/sbin/drpadmin
3. Answer the prompts as appropriate.
Verifying the RealPort Process: Linux
The RealPort daemon (process) controls communication between the
RealPort driver module and your Digi Devices across the network. One
daemon must remain in the background for each Digi Device, maintaining
the communication link. You should not need to start the daemon by hand.
The dgrp_cfg_node program does this automatically.
However, to determine whether any RealPort daemons are currently
running on your system, as well as to determine which Digi Device each
daemon is communicating with, you can execute the following command:
ps ax | grep drpd
For more information about the RealPort daemon, see the drpd man page
that is installed with the driver package.
Verifying the RealPort Daemon: SCO
Use this topic to verify that the RealPort daemon is running on a SCO Unix
or SCO OpenServer operating system.
1. At the root prompt, enter the following command:
ps ef| grep ncxd
If the RealPort Daemon is running, you should see an entry for each Digi
Device similar to the following.
