'''
Sniff stations on one set of radios using secondary radios.
make sure pexpect is installed:
$ sudo yum install python3-pexpect
$ sudo yum install python3-xlsxwriter
You might need to install pexpect-serial using pip:
$ pip3 install pexpect-serial
$ pip3 install XlsxWriter
The user is responsible for setting up the stations oustide of this script, however.
When specifying ports, if the port starts with [Number]., like 1.eth1, then the 1 specifies
the resource ID.
