Subject: rigol-ds: Send *OPC? after commands that don't return a value.
X-Git-Tag: libsigrok-0.5.0~71
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=ef7fb1abffad411c1bf20099228e4d23db402a81;p=libsigrok.git

rigol-ds: Send *OPC? after commands that don't return a value.

Fixes #933.

We'd already had this problem elsewhere and thus have this wrapper function
that does this where necessary. It just wasn't in use on these two call sites,
which was causing timing problems when used over tcp-raw or VXI transports.
