That will display a lot of asyn internal messages.  To just see I/O and error messages:
asynSetTraceMask("PORT", 0, 0x9)

> asynSetTraceIOMask("PORT", 0, 0xFF)

That will display raw and C-escaped, and hexadecimal versions of the I/O bytes.  For a standard ASCII message based device you’ll likely be happier with:
asynSetTraceIOMask("PORT", 0, 0x2)
