Storing received value from send, spawned telnet session
Hi Guys,
I'm completely new to bash and trying to write a script to spawn a telnet session to retrieve the RSSI value of my device and log the average value of the RSSI over 20 samples. I know that my command does return the RSSI value successfully but my bash scripting is letting me down.
I'm attempting to send the command, store the returned value over 20 samples and then averaging it - storing it in a log file.
Any help would be greatly appreciated.
Here's what i've got so far

How can I disconnect an existing telnet session? The host is a serial port server with multiple ports. The users login using the host's name and a port, i.e. telnet host01 1235.
