Pcanywhere DOS does this.

There is also a program on simtel called elsewhere which does (at least)
the console and may provide file transfer as wel, but I think I remember
its manual saying 'there are better programs for file transfer' so the
author didn't include that feature.  Could be wrong.

I bet, however, that the console access through the first serial port is
built into the bios.  You might consider making your own transfer
program.  Start a program on the sbc that writes console input to a file
until a special series of characters is received.  Start a program on
your side that sends the file via the serial portwith those characters
as an end of file indicator.

There are some rough edges to work out, but you could go all the way
toward implementing a full transfer protocol such as x/y/zmodem.

Since you are likely using a communications program already, start by
typing "copy con filename.ext" on the sbc, then sending whatever text
file to the SBC you want.  At the end of the transfer press "CTRL-Z" to
end the copy on the SBC.  You could encode binary files using UUENCODE
to transfer them as text files, then UUDECODE to convert them back to
binary on the sbc.  It's more work, but if you're transferring a lot of
stuff all the time then you'd simply go to your own set of programs (or
buy pcanywhere - though I don't think the current version supports DOS
anymore, you might need to call them and find out).

Also, the sbc probably has a parallel port - you might try using that
with laplink.  I'm assuming it doesn't have a network connection, but if
it does then I'd just use that.  It's easy to get connected to a windows
computer  from dos.

I hope this helps!
