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
