| parent | New file describing mc68681 libchip driver. (diff) | |
| download | rtems-4f0ffa57d8930fc835aba70fc61f52cda4f84810.tar.bz2 | |
Removed RTS and DTR handling code since the MC68681 seems to only have
automatic handling of RTS/CTS. This only protects the on-chip buffers
and FIFOs -- not the termios queues as the RTS/CTS code in here did. It
may be necessary in the future to enable this automatic support.
Interrupt processing code added.
In some places, channel and duart base addresses were swapped.
