    I had a hyperterminal set up for connection to my Electronic fuel injector, so that I can modify the injector program. This was working correctly. I bought another device that also requires a hyperterminal connection. I allowed a friend of mine to connect the device as he was familiar with its use. He removed the DB9 straight thru cable that I was using for the fuel injector & plugged in the required null cable to the same (only) DB9 connection to my computer. He set up the device and it works fine. However, when I open the program for the fuel injector, it gives me an error message that the controller code has been changed to something other than the needed code. (I assume this problem is due to the improper connection of the new device to the same connection on the back of the computer) I did some checking and found that both devices are using com port 1 (probably a no-no) . I have ordered an adapter to convert one of the required cables for these devices to an open DB25 connection on the back of the computer. ( It is difficult to exchange the cables as is) Once I get the adapter, I can leave both cables in place. What do I need to do to correct the present problem once I have the adapter and both cables in place? (I have created a second hyperterminal (icon only) for the new device.)

    Find out what code is needed for:

    he controller code has been changed to something other than the needed code

    Once you find out this and get it installed you should be ok It more than likely is one of the commands that open the modem and you would be best served by checking the manuals for the program and the modem.

    Ozromle, the required code is listed in the error mesage, so that won't be a problem. Am I correct in making a second connection & using a different com port number to prevent this from happening again?

    You would be able to do this if you have a second com port connector on the computer if you do not then you might have to purchase a PCI card with com ports on it to accomplish this. When you do this try to get teh modem oon com2 and then use either com 1 or com 3 for the other device and on the add-on com port board turn-off the com port that is not being used to avoid conflict of IRQ.
