Re: Multiple asyn ports inside asynPortDriver class

Hi Abdallah,

UDP and TCP use the same port number, not just the same IP address and physical port?  I don't think I have run into that before, so I can't see whether it has been tested with asyn.  You can turn on asynTrace on each port, and send them to different files to see if there are issues.

Subject: Multiple asyn ports inside asynPortDriver class

 

Hi

 

I am writing an EPICS driver for an Ethernet-based device in which the control interface is split between TCP and UDP layers of the same port number (i.e., registers IO is through UDP while waveforms is through TCP). I have to create two asyn ports using drvAsynIPPortConfigure function, so my question is are there any consideration regarding this approach? Because I am noticing some timeout issues, most likely from the device’s side, so I want to narrow the issue as much as I can. Thanks in advance.
