Alexandru Gagniuc e82d7dbc20 metex14: Print contents of received packet.
The packet is an ASCII string. We can simply print the raw packet data.

Alexandru Gagniuc 76b55dfa8a metex14: Fix parsing of spaces.
When the parser found a space, it treated it as an invalid digit
and discarded the whole packet. This behavior was incorrect on
2000 count devices, where the first digit can be sent as a space
rather than a '0'.

Convert spaces to '0' and parse them as usual.

Uwe Hermann 1fbab46626 metex14: Pass 'info' as a void pointer.
This is done so that the function prototype of all sr_*_parse() DMM
functions is the same, which will be needed later.

Bert Vermeulen 71caaad46b serial: allow for extra rts and dtr options in conn string
Options in addition to the usual "9600/8n1" syntax start with a
slash, and take the form of key=value, where different options are
also separated by slashes. For example:

	"9600/8n1/rts=0/dtr=1"

This sets RTS low and DTR high.

Alexandru Gagniuc a99e0d2a0c ols: Do not randomly probe serial ports
ols driver used to probe a series of available serial ports obtained
by regexp matching of common serial port names.
There are a number of problems with this approach:
1. It will probe all serial devices, including devices that do not
like to be probed, potentially causing them to act up.
2. It will try to probe serial ports which may already be opened in
other applications for other purposes.
3. It assumes the naming of the serial ports is set in stone, and
creates an unnecessary OS-specific list.
4. It produces unnecessary debug output even when an OLS device is
not connected.
5. etc...

Do not implicitly probe serial ports. Only probe the port specified
by the frontend, if any; otherwise, just quit.
Also get rid of all functionality in serial.c which was designed
specifically for random probing.

Uwe Hermann 133a37bfba Use g_try_malloc/g_free/g_strdup consistently.
Avoid plain malloc()/free() in sr/srd, especially in the API calls.
Also avoid g_malloc*() in favor of g_try_malloc*().

Use g_strdup() instead of strdup() so that we can use g_free()
consistently everywhere.

Exceptions: Stuff that is allocated via other libs (not using glib),
should also be properly free'd using the respective free-ing function
(instead of g_free()). Examples: Stuff allocated by libusb, libftdi, etc.

Also, use sr_err() instead of sr_warn() for actual errors. sr_warn() is
meant for non-fatal/uncritical warnings.

Uwe Hermann 1a081ca67d sr: Mark API functions with SR_API/SR_PRIV.
Use SR_API to mark public API symbols, and SR_PRIV for private symbols.

Variables and functions marked 'static' are private already and don't
need SR_PRIV. However, functions which are not static (because they need
to be used in other libsigrok-internal files) but are also not meant to
be part of the public libsigrok API, must use SR_PRIV.

This uses the 'visibility' feature of gcc (requires gcc >= 4.0).

This enables support for devices that have a different VID/PID

instead of always waiting for 2 seconds.

Uwe Hermann 548b08e55c Drop unneeded skeleton files.

useful examples already, no need for additional files.

Uwe Hermann 340f6e7aea Fix out-of-tree build.
Use libtool "noinst" local helper libs and use one Makefile.am per
subdir, which is the usual/preferred method. These helper libraries are
purely local and will not be installed.

This also fixes out-of-tree builds of sigrok, i.e. building in a
directory other than the sigrok source directory, e.g.

 $ cd /home/user
 $ git clone ...sigrok
 $ cd sigrok
 $ ./autogen.sh
 $ mkdir /tmp/foo
 $ cd /tmp/foo
 $ /home/user/sigrok/configure
 $ make
 $ make install

This will place all build results (.o files, .la files, etc) in the
local build directory (/tmp/foo) instead of the source directory
(/home/user/sigrok in this example). The installation directory is
selected via the --prefix configure option (/usr/local per default).
