It seems like the right way to fix this is to have your protocol file change the input EOS to ACK or NAK for those commands. 
 
Of course I agree that asyn should be timing out.  What happens when you do asynSetTraceTraceMask=255 on the underlying port driver?  Do you see the read request, and not see it timeout?

Subject: streamdevice problem with 1 byte reply



Hi,

For some commands, my device replies with only an "ACK" or "NAK",
no EOS.  Streamdevice gets the byte ok, then gets stuck waiting for
more input, but there is no more.

We are "still" using base 3.14.9, asyn 4.10 and streamdevice 2.4.
The replytimeout is set to 900, readtimeout is 100, maxinput is 0.

The problem seems to be asyn not timing out.  Could you guys advise
on what I may have missed?  Is there a quick fix, instead of upgrading
the whole complex to new versions?

Thanks much and best regards,
Dehong
