If your commands are only 4 bytes you might consider collecting
all four characters at once before actually looking at any
of them.

Since you want to waste time, going to a slower baud rate will
accomplish the same thing.   Even if it's not your favourite
solution it may help to prove to yourself that there's nothing
wrong with your software UART implementation.

It's almost never a good idea to try to implement time delays
with PC-based serial ports.  There is just too much virtualization
between the program and the actual hardware.  Recent implementations
of Windows have been observed to collect all the carefully
delayed characters and then blast them out in one shot.
