Subject: scpi-dmm: add "switch to local" support for Agilent protocol
X-Git-Url: https://sigrok.org/gitweb/?a=commitdiff_plain;h=118da66f8d8ab1ce2a60f429654f533df7f9ee08;p=libsigrok.git

scpi-dmm: add "switch to local" support for Agilent protocol

Send "SYST:LOC" to Agilent protocol speaking scpi-dmm devices at the end
of the probe (--scan) as well as in close (--show, --samples, etc). This
ends "remote" and re-enters "local" mode after programmatic use. Should
increase usability, eliminates the need for manual intervention before
subsequent DMM use. Was tested with a Keysight DMM. Does not affect the
HP protocol speaking devices.
