+Specifiying 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.
+
+Example:
+
+ $ sigrok-cli --driver <somedriver>:conn=<someconn>:serialcomm=9600/7n1/dtr=1
