Carriage Return in asyn record IEOS/OEOS fields

[Marissa Kranz via Tech-talk <tech-talk@aps.anl.gov>]

Hello,

I am using asyn records to send commands to ethernet connected power 
supplies. This particular supply requires \r for its end of string 
terminator. When I put \r into the IEOS or OEOS field in an asyn record 
and boot the IOC, the \r isn't instantiated in those fields- they are 
empty. I can dbput the \r in to those fields after the IOC is running to 
talk to the supply, but cannot get them to load at startup. I have 
confirmed that the \r exists in the .db files and tried using single and 
double quotes to get the \r to instantiate in the record fields with no 
success. These fields have worked for me in the past with terminators 
like \n, but I cannot get it work with \r.

The record documentation lists \r as the default value for the OEOS and 
IEOS fields, but leaving these fields blank to allow for the default and 
booting the IOC does not allow for communication with the supply. I have 
to explicitly dbput \r into the fields to be able to send and receive 
messages.

Has anyone encountered this is the past when using asyn and have a fix 
for getting the IOC to boot with \r in the OEOS and IEOS fields of asyn 
records?

Thank you,
Marissa Kranz
