Hi,
i have just take my mini2440 and having problem in communication with bios via serial port. using a desktop with serial port i have no problem. but using a laptop with a usb to serial converter i cant read the data. the setting are the same. i think this converter is not support 115200 baudrate because i am also using it with other devices with lower baudrates. i just want to try if i can change the baudrate of supervivi. i set the parameters to 9600 baudrate in supervivi menu but it is still comminucate with 115200. it didnot change what am i doing wrong?

I have found on some USB-Serial adapters, they dont stick to the baud rate set by the program opening the port, but instead use the baud rate setup in the driver.
On window, go into device manager and goto the properties for the COM port, it should have a tab that sets the baud rate. Try checking that, and/or setting it there.

Also, which menu item did you use in supervivi to change the baudrate ? ie. the letter.

I'm using this similar "blue" USB-RS232 converter (based on chip Prolific PL-2303) on desktop Windows 7 64bit, and works fine. Works fine on notebook (DELL XPS 1330) to. Every USB-RS232 adapters based on PL-2303 must work, i thing, because it's the best and high quality USB-RS232 converter chip.
