RE: TI-H: damaged link port?

Hi, 

  thanks a lot for response. I discovered what caused the problem before.
It was exactly the same thing, i.e. port pad was not correcly soldered and
fracutured somehow (but I do not remember that I dropped my calc or any
other simillar mishap). The reason why PC received data from TI but TI from
PC not, could depend on pin port that was broken. In my case it was GND.

I have damaged the link port in my 83 before, but that prompted a complete comms blackout rather than no response. I actually had to open up my calc and resolder one of the ports joints, as it had fractured. I'm not sure how common this is, but I dropped my calc with a link cable in it, and I  think that jogged the socket out of place a bit?

Hope this helps?

P.S : Anyone out there come up with any ideas re my previous comms problem involving the PC Link???

I would suggest you get the 92 emulator for your pc, and see if you can
get it working that way.
