Hi, Oleg.

pvFlush() will flush the SEQ PV layer, but maybe that's not what you're
asking about.

You can also do a synchronous put:

  pvPut(str_cmd, SYNC);

But still, I don't understand why str_rsp would ever contain one of the
commands from str_cmd (e.g. "I522") like your output shows, unless
something is messed up with what's happening in and beyond "{dev}StrCmd"
and "{dev}StrRsp".
