Review the port settings. Telnet to the IP address of the unit and login as root:
#> set port ra=*
Any port that is going to have a RealPort device attached, should have:
dev - Needs to be set to rp or prn.
auto - Needs to be set to off
NOTE: You can use the Web Interface to verify the device type as well.
#> set flow ra=*
Any port that is going to have a RealPort device attached, should have all signals off except ixon and ixoff (which can be on or off) and altpin (which should be off for a 10 wire Digi cables and on for anything else).
NOTE: You can use the Web Interface to verify the port setting as well.
#> set auth
Will show settings like the following:
Ind IPaddr Mask RealPort Login Unrestricted
1 0.0.0.0 0.0.0.0 oooo-ooo -------- oooooooo
o-oooooo -------- oooooooo
* Realport should show the lower case letter o for all RealPort ports. The ports are indicated across in groups of eight -- In the example above, all ports are set correctly in the RealPort column except ports 5 and 10 (which are possibly being used for non-RealPort connections as indicated by the hyphen (-) in position 5 and 10).
NOTE: This can only be verified in the command line.
Check for stuck processes:
At the Digi Device/Terminal Server root command prompt type:
* If a process (RealPort or otherwise) is running on the port try killing it, type:
#> kill tty=[port_number]
If this does not work, unplug the serial device and reboot the Digi Device/Terminal Server.
* Check the LEDs on the port to see if OFC is on this can be monitored using our DPA Remote software available for download from our web-site for a variety of operating systems:
