The issue is that the 7bit/7bit mode is counting to a 7bit number (127) 
before it rolls into the next byte. e.g.:

   "3" would be:     00000000 00000011
   "13" would be:    00000000 00001101
   "15" would be:    00000000 00001111
(so far so good)

   "16" would be:    00000000 00010000   (oops!)
   "100" would be:   00000000 01100100   (oops!)
   "127" would be:   00000000 11111111   (oops!)


What you need is:
   "15" would be:    00000000 00001111
   "16" would be:    00000001 00000000
   "100" would be:   00000110 00000100
   "127" would be:   00001111 00001111
