Re: Need to disable DTR on serial port

In any case, it turns out that one of the many requirements to get the
watch to respond is to have DTR disabled (done by setting fDtrControl =
DTR_CONTROL_DISABLE).  But apparently the default for linux is
DTR_CONTROL_ENABLE, and Wine will ignore any requests to change it
(DTR_CONTROL_HANDSHAKE being unimplemented as well)
Does this help?
