      Hi Shekhar.

      Not knowing what kind of USB to seral port you
      are using, I will check the parameters of the port for starters.

      This week we found out that the most recent
      update from Microsoft for Windows 7 disabled the PROLIFIC
      USB to seral adapter. It seems some of our club
      members acquired this USB/interface and they were
      all disabled. I can't recall where the info
      originated otherwise I paste the link. However
      the short term solution to this problem is by
      reverting to a previous Windows state before the
      upgrade. I don't know if this affects other USB
      adapters. I use Edgeport so far is working

      Good luck,

      I have a Prolific cable and a HL-340 cable. The Prolific does not work for anything. The HL-340 is giving the problem after the TNC establishes a connection.

        I have a Prolific cable and a HL-340 cable. The Prolific does not work for
        anything. The HL-340 is giving the problem after the TNC establishes a
        connection. Until then it works fine. The same cable when connected to my
        desktop computer work fine all the times...

        So, seems that it is not a cable problem. Below is a copy of what happens
        when I start the tnc and connect to my PBBS... At the end, it show the
        correct BBS output but stops responding to the keyboard inputs. TNC has to
        be powered down.

        The//Prolific PL-2302 chipset USB to serial adapters have been causing issues with Windows since Vista was released, and more of a problem with 64 bit Vista

          The//Prolific PL-2302 chipset USB to serial adapters have been causing
          issues with Windows since Vista was released, and more of a problem with
          64 bit Vista versions.
          Windows 7, 32 bit and 64 bit will do some weird things when using the
          Prolific PL2302 USB to serial adapters.
          Lots on the topic on the Baofeng UV-5R group trying to use the cheapo
          programming cable.
          I would recommend finding an FTDI chipset USB to serial adapter.
          The FTDI chipset has /Microsoft/ WHQL /certification/ for it's device
          and will operate fine under Windows XP, Vista, 7, 32 or 64 bit O/S versions.
          I personally use a sabrent FTDI USB to serial adapter with my KPC-2,
          KPC-3, KPC-3+, KPC-4 and KAM '98 and for programming my Baofeng UV-5RA
          under Windows 7,64 bit O/S without issues.
          They cost a little more, but you get what you pay for!
          Bottom line, stay away from the Prolific PL2302 chipset devices with
          later versions of the WINDOWS O/S!!!

          Try changing the CR2032 3VDC battery. It might read 3 VDC on a meter but if it is not fresh it can cause this fault. I had it happen to both of my KAMs.

              One of the significant problems with the "Prolific" devices are the clones that exist - most often found on eBay.
              I have 5 Prolific devices, all bought from a reputable supplier (CPC in the UK), at different times.
              I have never had problems on SBS2003, XP, Vista32 or Win7 32 & 64 with these devices.
              However, when I bought one from eBay, and I know of others who have done the same, we have ended up inadvertently purchasing Prolific "clones" and they never work and always end up getting sent back....

              So maybe the answer is choose FTDI, or Prolific, but buy from reputable sellers, they may cost a few $ more, but the extra you spend, you will save in time!
