Set the asyn trace flags to 0 for the port in question -- in particular the least-significant-bit which controls error-level messages.
From the IOC shell
asynSetTraceMask("<port>",-1, 0)
or use an asynRecord and a client of your choice.

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.
