After comparing the two setups for almost two days the solution turned out to be a very simple. For the benefit of others who might also face similar problem let me also tell what solved the problem. I was connecting the the LG2130 serial cable to the USB-Serial connection which was plugged into the USB cable that came with the coverter.This cable was plugged into another USB cable because I wanted the flexibility to change USB devices without accessing the backpanel. Once I connected USB cable from the USB-COM converter directly to the pack panel the problem went away. I am ruling out any problem with the USB cable to which connected the USB cable that came with the coverter to the back panel. That cable works fine when I connect any other device to using another cable. May be combination of three cables were bit too long to handle. Thanks Afsal

I was using serial cable with LG 2130 and it worked fine. Then I wanted to switch to using the the serial cable along with the USB to Serial convertor(prolific) because I wanted to rconnect on two machines and using USB was easy for plugging and unplugging. Now the issue it everything works fine on one machine. On the other machine, the connection goes through and after some minute or so connection hangs. After disconnecting the and connecting again, the same problem persists. On the other machine everything works fine. Both are Windows XP Pro machines. One is Lap top other is a desk top. Any clues as to what could be the issue here. Thanks in Advance. Afsal
