Hi John,I am thinking of a complete re-work of the error logging and debug output mechanism. This includes the possibility to switch on and off messages (debug and errors) for individual records and/or ports and to limit the amount of error messages and/or filter for error types. But this is non-trivial and takes some time.

All, I frequently encounter this situation and am wondering how to best address it: An IOC will have a device connected via StreamDevice. In my case it is typically a serial device connected though a serial-to-ethernet server. For some reason the serial device is not responding and the IOC console will have frequent "No reply from device" messages making it difficult to use the IOC console. These messages come from StreamCore which calls error() - defined in StreamError to print to stderr. I don't see any built in way to redirect these messages. I can imagine various changes but I am wondering what approach others may have taken or might suggest. Regards, John Dobbins Cornell University epics base R3.14.2 stream 2.5.1 asyn 4.19 linux-x86_64
