Version of smsd: (I work with subscriber units, I don't know the version of the SMSD)
Smsd installed from: from elsewhere...
Name and model of a modem / phone: Iridium 9523
Interface: serial
We have a system which allows sending SMS style messages over our satellite network. Your tool works great for testing messages <160,
but we support longer messages too. How difficult would it be to allow your tool to not do the length check when specifically requested, so I could generate longer PDUs for our system. (doing them manually make my teeth itch) 
Anyway, thanks for your time.
