Subject: center-3xx: Make serial write call block.
X-Git-Tag: libsigrok-0.4.0~967
X-Git-Url: http://sigrok.org/gitweb/?a=commitdiff_plain;h=c1da74fc0a345a01d5734ee93e035cf808803598;p=libsigrok.git

center-3xx: Make serial write call block.

This call is executed from an event handler and was previously nonblocking,
but has no partial write handling. It sends a short packet so should be OK
to block, most likely the output buffer will be empty anyway.
