Subject: atten-pps3xxx: Make serial write call block in scan.
X-Git-Tag: libsigrok-0.4.0~975
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=e7b4103697627bc985b77feb4c05dc67da8aebc0;p=libsigrok.git

atten-pps3xxx: Make serial write call block in scan.

This is called at scan time so free to block. There is no partial write
handling and a response is expected afterwards. This should therefore be a
blocking call.
