Library features a Sans-IO core with both asyncio and blocking wrappers:

from pandablocks.blocking import BlockingClient
from pandablocks.commands import Get

with BlockingClient("hostname-or-ip") as client:
    # Commands sent to Control port
    idn = client.send(Get("*IDN"))
    print(f"Hello {idn}")
    for data in client.data():
        # Data captured from Data port
        print(f"I got some PCAP data {data}")
