I have a newer laptop and PC without the connector for the DB-9 end of the blue Cisco cable. I've seen a USB cable with a male DB-9 end that looks as if it would work but I thought I'd post as someone may have a better answer. Again, I have the correct Cisco cable but it looks as if newer PC/laptops don't have the necessary COM port. Thank you.
You should be fine with a USB to male DB-9. This is a very common workaround for those without available COM ports on their machines. When you use these, your PC or Laptop will most likely recognize it as a virtual COM port. Therfore, your terminal software won't skip a beat and shouldn't require any further configuration or tinkering.
As far as finding one that works with your PC or laptop, be sure to read some reviews online before making any purchases to make sure you don't have any issues with your terminal software.
Hope this is helpful!
