Popen - How can I read data before CTRL+C command is issued

[maffaz]

I can handle the Exception no problem.

The problem I have is that I want to issue the CTRL+C command upon hitting a certain device.

I cannot read the data until the CTRL+C command is sent and the tool exits..

I want to read the data and issue a CTRL+C command if that data is the data I require. in this instance 'device2'.

so my ideal solution is:

1. start command.

2. read each line and append to a list.

3. after each line is appended, check the list for 'device2'

4. if 'device2' is in that list, issue a CTRL+C command.

5. then I can assign that line to a variable and use it to update the firmware.
