    Posted: February 10 2015 at 7:52am
We are using the Accuterm 7 on a windows 7 64 bit computer and connection is through serial port on the computers and the serial ports are either via USB adapter or installing serial ports in the PCI E+. Now everything works perfect other than if you hit any key or enter button on the key board the connection drops and you have to hit the reset connection button every time after you hit a key. I have tried all sorts of settings and also tried many different drivers. 64 bit is the major issue. We have made this work with 32 bit but one computer is always different than another and it take a different adapter with a different driver every time. I have only been able to make one 64 bit computer work so far and cannot use of those setting to make it work on any other computer. Serial port is the only way we can go as our server can only be accessed this way. There has got to be something I am missing that will make this work as everything else works fine other than a keystroke drops the connection. What am I missing?

Hi Matt -

I would have to say it has to be a hardware / driver issue. I have on-board serial ports on my PC and they work perfectly running Windows 7 64-bit. You might try a free or demo version of another serial-port enabled terminal emulator to see if it has similar issues. If so, then this clearly points to the hardware / drivers.

Thanks,

Pete

Do you happen to know what serial ports you are running and maybe I can try those with their software. I seem as if I am up against a wall with this all the time

Hi Matt -

The serial port on my development machine is built into the motherboard (Asus P6T) and I don't know what chipset is being used. I did a quick test of a USB serial port adapter cable that I have and it also works fine on my Windows 7 64 bit development machine. The cable brand is Sarbent, and the chipset is FTDI. I'm use other manufacturers use the same FTDI chipset. I think I also have USB serial adapter cable which uses the Prolific chipset but I cannot locate it to see if it will work in Windows 7 64 bit.

Thanks,

Pete

Pete,

I tried the Sarbent adapter and it works right off the bat. I don't know why the other 5 kinds I tried would not work but this one did. thanks for the help.

Hi Matt -

Glad you found an adapter that works now. These USB-Serial adapters seem to be very inconsistent.

Thanks,

Pete
