Finally, this source uses the inetd superserver to create a simple network server that will echo any characters received back to the client. This can be demonstrated by telnetting into the host board and typing some characters.

//echo.c

//All this file does is echo any data written to its standard

//input to it’s standard output. If run from the commandline

it

//will echo typed characters. If you add this line to your

///etc/inetd.conf file

//

//24 root tcp nowait /path/to/echo

//And then try to telnet to port 24 of your dimmPCI develop- ment

//board it will echo any charcters sent via the telnet

//connection.
