Title: SIMULATED SERIAL DRIVER
Description: The simulated serial driver has some odd behavior. It
will stall for a long time on reads when the C stdio buffers are
being refilled. This only effects the behavior of things like
fgetc(). Workaround: Set CONFIG_STDIO_BUFFER_SIZE=0, suppressing
all C buffered I/O.
Status: Open
Priority: Low (because the simulator is only a test/development platform)
Title: SIMULATOR NETWORKING SUPPORT
Description: I never did get networking to work on the sim Linux target. On Linux,
it tries to use the tap device (/dev/net/tun) to emulate an Ethernet

/* Clean up */
UPDATE: I recently implemented a good UART simulation to driver
the serial console. So I do not believe that problem exists and
I think that the above workaround should no longer be necessary.
However, I will leave the above text in place until I get then
oppotunity to verify that the new UART simulation fixes the problem.
