During the execution of the mt command, it may be desirable for a read operation to
I/O space to follow each write and read operation in the test. This could detect
potential problems in the memory controller where memory and I/O accesses are
handled. This command does not print the data from the read operation to I/O space.

! Follow with reads beginning at this address.
If the follow-with-write flag is also enabled, the additional address requested is used
for this write operation and the read operation is performed from the first address. In
the following example, two blocks of memory are filled with their own addresses
and read operations from the first block are displayed after each write operation to
the first block.
