Instead of using a parallel port I think I'll use an NE 2K card. The
only problem is I don't know how to program the thing.
Could someone do me a favor and tell me how to like send a signal each
direction using an NE 2K card? Plex86 includes an NE 2K emulator. I need
to know how to do this because a parallel can't support the bandwidth.
There will be _no_ OS on one end (the "slave" PC) but on the other end
there will be an OS that lets me directly program the thing.
It'd even be helpful if you explain how to do this from the point of
view of the NE 2K emulation source code; I can look at the source and
find out what port I/O would correspond to what functionality.
I know how to write a serial communications driver and I'll use serial
at 230400 bps if I can't directly program the net card. If anyone could
point me to some docs on the net, that'd be helpful too. Where'd Kevin
learn how to make an NE 2K emulator? I just need some specs or
something...
BTW to do 230400 bps via serial I'm going to use RTS etc. as a data bit
too so it will _really_ be "parallel-serial" (since 2 bits in one
direction will happen at once). The protocal won't be able to send both
directions simultaniously (no need to; only thing that'd help for is DMA
which is being emulated anyways).
Thanks in advance
