Alexandru Gagniuc 7c41dc4774 radioshack-dmm: Implement support for "LOGIC" mode
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).

Alexandru Gagniuc be8dbf3ab2 radioshack-dmm: (Trivial) Convenience fixes
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.
