@c FIXME: What if anything needs doing to match the "n,8,1,none" part of

@c for character size. Taken from stty maybe...? John points out tip
@c can set these as internal variables, eg ~s parity=none; man stty
@c suggests that it *might* work to stty these options with stdin or

Using the @samp{tip} or @samp{cu} connection, change the DOS working
directory to the directory containing a copy of your 29K program, then
start the PC program @samp{EBMON} (an EB29K control program supplied
with your board by AMD):

For this example, we've assumed what is probably the most convenient
way to make sure the same 29K program is on both the PC and the Unix
system: a PC/NFS connection that establishes ``drive'' @code{g:} on the
system: a PC/NFS connection that establishes ``drive @code{G:}'' on the
PC as a file system on the Unix host. If you don't have PC/NFS or
something similar connecting the two systems, you must arrange some
other way---perhaps floppy-disk transfer---of getting the 29K program
