RE: Multiple asyn ports inside asynPortDriver class

[Abdalla Ahmad via Tech-talk <tech-talk at aps.anl.gov>]

It seemed to be an issue with the device itself, the device’s own software produced the same timeout behavior on continuous TCP requests. I have another question, right now I am relying on asyn’s address as the register’s address on the device but I think the driver could be designed in a better way, can you give pointers on how to parse asyn parameter strings and create corresponding asyn parameters?

 

Thanks!

Abdalla.

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.

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.
