I've pushed fix for sendsms command to achemeris/sms-split branch at
SourceForge repo. Attached is the same patch for OpenBTS-UHD - it's
not tested, because I can't get OpenBTS-UHD to work with my USRP1, but
it compiles and I'm pretty sure it works.
Now we have two commands - "sendsms" which behaves as intended and
"sendsmsrpdu" which accepts a hex string of RPDU.
OpenBTS> sendsmsrpdu 250015280089195 123
enter text to send: 014603a1000000138003a121f30000117042711404e104d4f29c0e
OpenBTS> sendsms 250015280089195 123 0000
enter text to send: Test
(two commands above are equivalent)
