To use the Digi so that the serial device that is plugged into it shows-up on a machine looking just like a regular serial device.  There are other configurations as well, e.g. PPP.

−
For HIP and weather we need to use image as the server since it runs Linux (Digi doesn't speak BSD) and it is generally up and has plenty of cycles.
 
−
 
 
−
Install the software (see CharlieP for the details)
 
−
 
 
−
This version of the Digi software does not work with the 2.6.x kernel, it would zorch the machine (no console output, nothing) when you accessed the device. 
 
−
 
 
−
Configure DHCP and DNS for the device.  Depending on how it will be used you may need 1 or more IP numbers for it.  159.28.230.108, ets1.cs.earlham.edu

−
Installing the kernel module:
 
−
        insmod dgrp
 
−
 
 
−
Use Digi RealPort Manager to add the device to the machine where it will be "homed" (image in this case).
 
−
        /usr/bin/dgrp/config/dgrp_gui
 
−
       
 
−
        device id should be rp, it will append port numbers, i.e. ttyrp00, etc.

        one per port (2 in this case).

−
Checking to see if the daemons are running:
 
−
        ps auxw | grep dgrp

−
To start the daemons (once the kernel module is loaded):
 
−
        /etc/rc.d/init.d/dgrp_daemon start
 
−
 
 
−
To stop the daemons:
 
−
        /etc/rc.d/init.d/dgrp_daemon stop; rmmod dgrp

−
Web interface for configuration

Telnet interface?

dinc rather than tip, cu, etc.
 
−
        dinc -18N /dev/ttyrp00

        ~DEL is dinc menu, ~X exits dinc
