What is the purpose of the above two variables?

What are you trying to accomplish in this one?  on the huawei driver
this is used to re-open the tty because it is HUP-ed when the ppp
session ends (their way of signaling NO CARRIER).  However, I don't see
you doing PPP yet, so I'm not so sure of the purpose here?

So enable and disable just open up the ports?

I'm lost here.  What are you trying to accomplish?
