Thank you for your offer. I would be glad if you could help me.
So far I have tried to add line to the tcpip.py as suggested by the post (sent link)
You are using the DS1054Z module, which uses python-vxi11, right? Which tcpip.py did you modify?
To modify the TCPIP flags as used by Python-VXI11, you'd probably need something like:
import socket
ds1054z = DS1054Z(...)
ds1054z.client.sock.setsockopt(socket.IPPROTO_TCP, socket.TCP_NODELAY, 1)
But also note RoGeorge's point about possible issues with Windows. I don't know anything about that.
