[SR-Users] KEMI - Set message body to Bytes / Prevent parsing PV?

[Daniel-Constantin Mierla]

Hello,

using KSR.pvx.evalx("$uac_req(body)", "$smsbody") works fine as long as
there is no '$...' inside $smsbody, because the second parameter is
evaluated twice for variables. That's the reason I gave the example with
$$(smsbody), so first time $$ is evaluate to $, resulting in $(smsbody),
which is then evaluated again.

Cheers,
Daniel
