Hanging where?  Which line? You'd get a lot more helpful
answers if you provided details about what your program is
doing rather than vague statements like "it doesn't work" or
"it's hanging".

You also need to post the actual code that you're running.
Since it didn't used to hang and it does now, you have
presumably changed it.  We don't have any way of knowing what
code you're running, so how can we tell you what's wrong?

I don't know what "the write function is not making it through"
means.

Like I said before: are you _sure_ you don't need to terminate
the commands with a carriage return?  Do you understand that
question?  After you type a command in Hyperterminal do you
have to press [Enter] in order to get a response?  If so, you
need to append a carriage-return to the end of the command
strings you're writing like this: 'command parameter1 parameter2\r'
