Size* Comments
Standard 7-bit ASCII Y 7 2.8 Produces the largest file with the
slowest transmission speed, but
offers the best portability to other
hosts. Can be treated as a text file.
Compressed 7-bit ASCII with
runlength coding
compression Y 7 1.71 High compatibility with most
ASCII-oriented hosts. Can be treated
as a text file.
Binary 8-bit ASCII with
runlength coding
compression Y 8 1.04 Less compatible for porting to other
hosts than Standard or Compressed
format. Can be treated as a text file.
Produces a small hex file.
For very compressible data, this
option may produce the best results
Transparent Raw N 8 1.14 Produces one of the smallest, but
also the least compatible hex files for
porting to other hosts. Does not use
compression. Cannot be treated as a
text file. For images that don’t
compress easily, is best choice for
size and transfer speed using direct
serial link. Use Transparent if you
plan to create your own program
loader for transferring the hex file to
the PDT 3400 and don’t need
software flow control.
* Approximate hex file size as a multiple of the image size.
