Subject: [PATCH] remote target interrupt before ack
Date: Mon, 04 Apr 2011 20:00:00 -0000	[thread overview]
Message-ID: <201104042200.15473.michael@walle.cc> (raw)

Hi,

the following patch puts the sending of the interrupt/break sequence before 
the proforma ACK. This guarantees the ACK won't be delivered to an application 
on the remote side.
