One of our main requirements for micro to mainframe communication is
to be able to archive programs on the large systems disks.  This
includes binary files that may be .COM, .EXE, .CMD and "squeezed"
files.

KERMIT for TOPS-20 only saves files as 7-bit ASCII, which loses the
eigth bit.

Under MS-DOS files can have a length that is not an even multiple of
128 bytes.  MODEM loses because a file that is transferred up to the
HOST and then back to the PC will be rounded up to the next even
number of sectors.

I know there are programs that will expand binary files to 7-bit files
but I do not think that extra translation is a good solution.

Comments?

Ted.
