You only need to restart the IOC once and set IMAX=1024 or some other size that will always be large enough when you load asynRecord.db.  You then set the input format (IFMT) to "Hybrid" which uses the large BINP buffer but still does EOS processing.

Subject: Reading multiple lines from an asyn record

I have an asyn record to a device:

https://epics.anl.gov/modules/soft/asyn/R3-2/asynRecord.html

I would like to download files from this device to my computer, that consist of carriage return separated lines. The problem is the 40 character limit. I see that if I use BINP I can adjust the character limit if I restart the IOC, but ideally I would like to avoid this.

Is there a way to get the record to read one line at a time? If I could somehow get every line of the file read with a camonitor of the PV this would be good enough for me.
