-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.

+UNI-T UT-D04 cable issue on Windows
+-----------------------------------
+
+There have been reports that CH9325 based cables are not detected on
+Windows out of the box when they are assigned to libwdi drivers. Though
+they may be usable in that case when the USB address is manually specified.
+This can happen when some "USB to serial" driver is assigned which does not
+provide a genuine COM port that enumerates naturally. Manually assigning a
+"USB input device" driver can improve HIDAPI compatibility and make the
+cable show up in sigrok's serial port enumeration.

+
+Enabling multimeter / data logger measurement output
+----------------------------------------------------
+
+Some multimeters or data loggers will not start outputting measurement data
+unless a certain action has been performed by the user beforehand. This is
+usually mentioned in the vendor manual of the respective device, but here's
+a short list for convenience:
+
+ - BBC Goertz Metrawatt M2110: Briefly press the "Start/Reset" button on the
+ interface panel on top.
+ - Brymen BM257s: Press HOLD during power-on.
+ - Digitek DT4000ZC: Briefly press the "RS232" button.
+ - EEVBlog 121GW: Hold "1ms PEAK" until the "BT" indicator is shown.
+ - ES51919 based LCR meters (DER EE DE-5000, PeakTech 2170, UNI-T UT612):
+ Press the button with the "RS232" or "USB" or "PC link" label (usually
+ the "up" cursor button).
+ - Gossen Metrawatt Metrahit 1x/2x devices, driver gmc-mh-1x-2x-rs232:
+ - Power on the device with the "DATA" button pressed.
+ - Metrahit 2x devices must be configured for the respective interface type.
+ - Gossen Metrawatt Metrahit 2x devices, driver gmc-mh-2x-bd232:
+ - 'BD232' interface:
+ The multimeter must be configured for the respective interface type.
+ - 'SI232-II' interface ("PC Mode"):
+ The multimeter must be configured for interface type 'BD232' (all),
+ 'SI232 online' (28-29S) or 'SI232 store' (22-26x). The interface must
+ be configured to the same baud rate as the host (default 9600).
+ Multimeter and interface must be configured to the same address.
+ - GW Instek GDM-397: Press the "REL/RS232C (USB)" button for roughly 1 second.
+ - GW Instek VCP: See the discussion on manual driver assignment to common
+ USB to UART chips with non-default USB identification.
+ - MASTECH MS6514: Press the "Setup/PC-Link" button for roughly 3 seconds.
+ - Meterman 38XR: Press the "RS232" button.
+ - Metrix MX56C: Press the PRINT button to have the meter send acquisition
+ data via IR. Hold the PRINT button to adjust the meter's transmission
+ interval.
+ - Norma DM950: If the interface doesn't work (e.g. USB-RS232 converter), power
+ on the device with "FUNC" pressed (to power the interface from the DMM).
+ - PCE PCE-DM32: Briefly press the "RS232" button.
+ - RadioShack 22-812: Press and hold "SELECT" and "RANGE" together.
+ - TekPower TP4000ZC: Briefly press the "RS232" button.
+ - Tenma 72-7750: Briefly press the "RS232C" button.
+ - UNI-T UT60G: Briefly press the "RS232C" button.
+ - UNI-T UT61B/C/D: Press the "REL/RS232/USB" button for roughly 1 second.
+ - UNI-T UT71x: Press the "SEND/-/MAXMIN" button for roughly 1 second.
+ Briefly pressing the "EXIT" button leaves this mode again.
+ - UNI-T UT181A: In the "SETUP" menu set "Communication" to "ON".
+ - UNI-T UT325: Briefly press the "SEND" button (as per manual). However, it
+ appears that in practice you don't have to press the button (at least on
+ some versions of the device), simply connect the device via USB.
+ - V&A VA18B/VA40B: Keep the "Hz/DUTY" key pressed while powering on the DMM.
+ - Victor 70C/86C: Press the "REL/RS232" button for roughly 1 second.
+ - Voltcraft VC-830: Press the "REL/PC" button for roughly 2 seconds.
+ - Voltcraft VC-870: Press the "REL/PC" button for roughly 1 second.
