             INT 15,2 - Read Blocks from Cassette (PC,PCjr only)

       AH = 02
       CX = count of bytes to read
       ES:BX = pointer to data buffer

       on return:

       AH = error code if CF=1
          = 1  if CRC error
          = 2  data transition lost, (bit signal scrambled)
          = 3  no data found on tape

       DX = count of bytes actually read
       ES:BX = pointer to byte following last byte read

       - data is transferred in 256 byte blocks, though only the
         number of bytes requested are actually stored
