I had this same problem. I think it's because the serial driver
automatically gets unloaded when it's no longer used, and then when it
gets reloaded, it's reset.
There are two ways I found around it:
1) Add a line that says "serial" to your /etc/modules file, so that the
serial module gets loaded at startup and stays loaded.
2) Recompile the kernel with the serial driver compiled in (rather than
as a module).
