We have been working on writing an IOC on a Linux running EPICS

3.14.8.2 and Asyn 4-4 the last few days trying to connect to an RS-422

serial device that sends out signal 4 times a second.  The device is a

home made device, but it sends out ASCII character to its serial port.

While we have no problem reading the ASCII values in the terminal

emulation program, we are having a problem trying to read the stringin

under EPICS.  It reads about a second or two, then, we get

segmentation fault.  We have adjusted the scan rate and time-out

values in the device support, but we can't seem to get this right.

Does any body have an idea how to deal with this??
