There are already functions in the AT driver that handle this - check out 
at2_encode7bituncompressed() and at2_decode7bituncompressed(). maybe these 
should be moved to the sms.{h,c} files.

you have to do this for GSM modems as they speak directly "on the wire". all 
SMPP SMSCs I've talked with do this for you so you don't need to worry about 
it.

See AT driver.
