Re: StreamDevice support problem: Cannot find a bus named 'L0' for...

[Hasan SANSAR via Tech-talk <tech-talk at aps.anl.gov>]

Hi Mark,

Thank you. The problem is reduced. I still can't connect to power supply. Can it be caused by virtual network (bridged network)? But I can get ping including transmitted and received packages. I think this cannot origin of this problem. Port numbers are written in power supply's manual that 8003 for TCP and 8005 for UDP. There are outputs of st.cmd file and ping command.

I installed EPICS R3.15.8.1-DEV from LaunchPad that given 'git' command on epics-contols.org and also StreamDevice and asyn from GitHub, and so I applied instructions on docs.epics-controls.org and there is no problem for installation and for example of creation IOC.
