Hi Andrew,

I recently taught a class on asyn where we did a hands-on exercise writing a driver that communicates with a Newport XPS using the drvAsynIPPort as the underlying transport.

The handout is here:
http://www.aps.anl.gov/epics/docs/APS2015/10-AsynDriver-Lab.pdf

A tar file with the example driver fully worked out, and a template driver as an exercise for the students can be found here:

The lecture slides and YouTube videos of the classes are here:

Let me know if you have questions.

Mark

Subject: Example asyn device support for rs-232 hardware with unsolicited messages (without using stream-device)

Hi,

I tried searching the on the APS list of hardware here (http://www.aps.anl.gov/epics/modules/bus.php#RS%2d232%20%28Asyn%29) but I am having trouble finding an application that fits the above description.

I would like to use it as a template to write support for a tricky device I am working with (which works with stream device 95% of the time but produces some occasional problems due to unpredictable ordering of output messages as well as grouping unsolicited messages with solicited output).

If anyone could  point an example application that does not use stream device that would be great.

Thanks,

Andrew
