I have a Kantronics KAM all-mode TNC. For the "computer" connection I've been using the 25way "D" connector on the KAM to the 9 way "D" serial port on my old laptop. Works fine. Now I have a newer laptop, I notice there is no 9 way "D" serial connector on it - only USB. (I think the 9 way "D" serial connectors are obsolete).
Question: "What is involved in 'converting' the existing serial interface to USB or is it even possible?
Thanks for any thoughts/answers.
