Every serial device's driver has default serial port parameters like baud
rate, number of data bits, stop bits and handshake status. If a device requires
different parameters, pass them as option "serialcomm" with the driver name.

-ALSA driver
------------
-
-The 'alsa' driver can be used to sample analog data using a PC's soundcard.
-I.e. the sound card can act as a simple oscilloscope (with some limitations)
-using commercial or DIY "sound card scope probe" cables.
-
-Since ALSA is a Linux-specific sound system, this driver will inherently
-only compile and work on Linux.
-
-We might write additional drivers to make a similar functionality available
-on other OSes at some point.
-
-
-Link Instruments MSO-19
------------------------
-
-The driver for the Link Instruments MSO-19 mixed-signal oscilloscope (MSO)
-is currently using libudev (which is a library for the Linux-specific udev
-system). Thus, this driver can currently only compile and work on Linux.
-
-We plan to fix this though, so that it'll work on all other OSes, too.

OLS
---
-The Dangerous Prototypes Openbench Logic Sniffer (OLS) logic analyzer is
-supported by the 'ols' driver in libsigrok. This driver assumes a somewhat
-recent firmware has been flashed onto the OLS (it doesn't need a firmware
-upload every time it's attached via USB, since the firmware is stored in the
-device permanently).

-Rigol DS oscilloscopes
-----------------------
-
-The 'rigol-ds' driver (for the Rigol DS series DSOs) currently uses the Linux
-usbtmc kernel driver. This means it can currently only be built and used on
-Linux (i.e., it's non-portable).
-
-The use of a kernel module also means it is dependent on the kernel version
-used, as well as on whether this specific module is available in the kernel.
-Additionally, the usbtmc kernel module has been known to have various bugs
-in some versions. These are some (but not all) drawbacks of using a kernel
-module as opposed to a libusb-based driver that works in user-space.
-
-We plan to change the driver to use the 'librevisa' user-space shared
-library (which uses libusb) soon, which will fix all these issues and make
-the driver portable at the same time.
