I spent the last half hour googling with no success. What does the "b"
mean and how is it controlled?

Perhaps I did not make that clear, I refer to the the "b"  in "brw-rw----."


The first character in an "ls -l" is the type of file. From the info
page (info ls...navigate to "What information is listed"):

     The file type is one of the following characters:

     '-'  regular file
     'b'  block special file
     'c'  character special file
     'C'  high performance ("contiguous data") file
     'd'  directory
     'D'  door (Solaris 2.5 and up)
     'l'  symbolic link
     'M'  off-line ("migrated") file (Cray DMF)
     'n'  network special file (HP-UX)
     'p'  FIFO (named pipe)
     'P'  port (Solaris 10 and up)
     's'  socket
     '?'  some other file type
