The Fortune Semiconductor FS9721_LP3 and FS9721B/Q100 DMM chips are very
similar and the protocol looks identical.
Tested on a Voltcraft VC-820 (FS9721_LP3) with the uni-t-dmm driver
(needs some small changes, tbd).
Turn TODOs which should be user-visible into @todo so that Doxygen
shows them in the function docs, and also on the special "Todo List" page.
Those TODOs that should not be in the Doxygen docs are moved out of the
/** */ comment blocks.
Also fix some comments/items, and remove some obsolete ones.
- Turn SR_OK/SR_ERR_* and SR_LOG_* into proper enums.
- Use /**< Foo. */ for Doxygen comments that are on the same line as
the (e.g.) enum entry they document. If the comment is not on the
same line (but rather directly above the enum entry) a simple
/** Foo. */ comment is sufficient.
- Use /** */ instead of /* */ in some places, so that Doxygen actually uses
the respective comments.
- Various smaller cosmetic fixes or cleanups.
- Show a short project description, the libsigrok version (x.y.z or
"unreleased development snapshot"), and the sigrok logo in the
Doxygen output.
- Ignore a bunch of files and directories which don't contain public
libsigrok API anyway.
- Remove the SR_API prefix from the Doxygen output (all
functions/symbols in the output are part of the public API anyway).
- Various changes of settings to get nicer and more useful output.
LOGIC mode sends the following data:
V < 0 : actual voltage
0 <= V < 1 : LOW
1 <= V < 2 : actual voltage
2 <= V : HIGH
We follow the same idea, and set our unit to BOOLEAN for the crazy
case (HIGH or LOW).

While testing the new radioshack-dmm driver with pulseview, I found
a few inconvenients.
1. Print an info message when a port is probed, and when a device is
found. This makes it easy to tell if and where the driver is looking.
2. num_samples was not reset after the first aquisition, so the
second aquisition would quit right away. Reset num_samples at start
of a new aquisition.
3. There's no need to open the serial port RW, so change O_RDWR to
O_RDONLY when opening the port.
These changes are too trivial to split into different patches.
