.SH "DESCRIPTION"
-.B sigrok\-cli
-is a cross-platform command line utility for the
-.B sigrok
-logic analyzer software.
+\fBsigrok\-cli\fP is a cross-platform command line utility for the \fBsigrok\fP software.
.PP
The command-line frontend for sigrok cannot display graphical output, but is
still sufficient to run through the whole process of hardware initialization,
It is useful for running on remote or embedded systems, netbooks, PDAs,
and for various other use-cases. It can display samples on standard output or
save them in various file formats.

+\fB\-\-driver\fP <drivername>
+A driver must always be selected. Use the \fB-V\fP option to get a list of available drivers. Drivers can take options, in the form \fBkey=value\fP separated by colons.
+.sp
+Drivers communicating with hardware via a serial port always need the port specified as the \fBconn\fP option. For example, to use the Openbench Logic Sniffer:
+.sp
+.RB " $ " "sigrok\-cli \-\-driver=ols:conn=/dev/ttyACM0"
+.sp
+Some USB devices don't use a unique VendorID/ProductID combination, and thus need that specified as well. This also uses the \fBconn\fP option, using either \fBVendorID.ProductID\fP or \fBbus.address\fP:
+.sp
+.RB " $ " "sigrok\-cli \-\-driver=nexus-osciprime:conn=04b4.8613"
.TP
.BR "\-d, \-\-device " <device>
-The device to use for acquisition. It can be specified by ID as reported by
-.BR "\-\-list\-devices" ,
-or by the name of the driver as reported by
-.BR \-\-version .

Save output to a file instead of writing it to stdout. The default format
.BR "\-p, \-\-probes " <probelist>
A comma-separated list of probes to be used in the session.
.sp
+Note that sigrok always names the probes according to how they're shown on the enclosure of the hardware. If your logic analyzer numbers the probes 0-15, that's how you must specify them with this option. An oscilloscope's probes would generally be referred to as "CH1", "CH2", and so on. Use the \fB\-\-show\fP option to see a list of probe names for your device.
+.sp
The default is to use all the probes available on a device. You can name
a probe like this:
.BR "1=CLK" .
Example:
.sp
$
-.B "sigrok\-cli \-\-samples 100 \-\-probes 1=CLK,2\-4,7"
