Yes, it's possible to send a string to a device in telnet, but I believe the only strings you will see in telnet are those sent to device 0. If you want to see a device's responses in telnet, you probably need to put some code in the string handler of a data event to send the returning string to device 0.
You can try the REDIRECT_STRING command. I've tried it without success.
If you don't need to do it in Terminal or Telnet, you can do it in Netlinx Studio. Click on Diagnostics->Control a Device. You can monitor in Notifications/Diagnostics.
