Gerhard Sittig 66c300c4a6 serial-lcr: also request packets before initial state retrieval
Commit cb5cd1538f introduced packet request support in the serial-lcr
device driver. Calls were added to the detection of the device's
presence, and the periodic acquisition of measurement data. Add another
call to the device configuration retrieval that follows the presence
detection, without it communication timed out with no data received.

Also slightly raise the timeout for this device configuration gathering
phase. With one second sharp, the VC4080 was detected, but getting its
current configuration kept failing. This device's serial communication
is extra slow (1200 bps) and the packets are rather large (39 bytes).
Which made the stream detect's receive routine stop checking for the
availability of more data while a packet was being received.

README

-------------------------------------------------------------------------------
README
-------------------------------------------------------------------------------

The sigrok project aims at creating a portable, cross-platform,
Free/Libre/Open-Source signal analysis software suite that supports various
device types (such as logic analyzers, oscilloscopes, multimeters, and more).

libsigrok is a shared library written in C which provides the basic API
for talking to hardware and reading/writing the acquired data into various
input/output file formats.


Status
------

libsigrok is in a usable state and has had official tarball releases.

While the API can change from release to release, this will always be
properly documented and reflected in the package version number and
in the shared library / libtool / .so-file version numbers.

However, there are _NO_ guarantees at all for stable APIs in git snapshots!
Distro packagers should only use released tarballs (no git snapshots).
