-Specifiying serial port parameters
-----------------------------------
+Specifying serial port parameters
+---------------------------------
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.
-See libsigrok docs for function serial_set_paramstr() for complete specs.
+See libsigrok docs for the function serial_set_paramstr() for complete specs.
Example:
- 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 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.
-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.
+ChronoVu LA8/LA16 USB VID/PIDs
+------------------------------
-We plan to fix this though, so that it'll work on all other OSes, too.
-
-
-ChronoVu LA8 USB VID/PIDs
--------------------------
-
-The ChronoVu LA8 logic analyzer is available in two revisions. Previously,
-the LA8 shipped with a USB VID/PID of 0403:6001, which is the standard ID

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.
