# The erc32 console driver can operate in either polled or interrupt mode.
|
|
# Under the simulator (especially when FAST_UART is defined), polled seems
|
|
# to operate better. It is common for a task to print a line (like the
|
|
# end of test message) and then exit. In this case, the program returns
|
|
# control to the simulator command line before the program has even queued
|
|
# the output to the uart. Thus sis has no chance of getting the data out.

# the wall time required to execute the RTEMS test suites.
