Re: TI-H: $4 Serial Link won't work




you should have the link program running on the pc when you connect.  and i
usually try to be in the link menu on the calc already.

its pretty normal for the calc to apparently "lock-up" wehn you plug in the
link with no pc program running that initializes the link port.

 i think your link is fine.
