This is a python based Alfred flow.

This workflow probes for open TCP ports, it reveals if the port you specify is open or closed. If open, it reports latency. If, instead of a port number a dash '-' is given, the workflow will check ports 22, 80 and 443, reporting latency for each open one.

Format is keyword 'pp' followed by host<space>port

where:

• host is hostname or IP address,
• port is a numerical value or -
