Read Data
FORM3 has an eight-byte header to deal with. The rst two bytes are the ASCII characters
#6. This indicates that a xed length block transfer follows and that the next 6 bytes form an
integer specifying the number of bytes in the block to follow. The header must be read in so
that data order is maintained (lines 260 and 300).
At the data end, the terminator \
^
" is sent(lines 280 and 320).
