How to set communiction time outs and DCB structure. This sample uses COM1: and COM2:. So you have to disable serial debug output (by step into the bootloader and type "O" ... ) and to remove ndcucfg from autostart (registry key HKLM\Init). Instead of this you can modify the program and use COM3: (connection between RX and TX).

Hello,
I'm trying to use the COM1, but it doesn't works. I've disabled the debug output (with command "O" in the bootloader), but I don't know how remove ndcucfg from autostart. How can I access to the "registry key HKLM\Init"??
Thanks! -
Hello,
you can use "ndcucfg" itself for this purpose! Note, you can run "ndcucfg" not only via serial line. E.g. open telnet- or cmd shell and enter "ndcucfg".For delete "ndcucfg" from autostart do following:
PS: you can redirect "ndcucfg" to an other serial line under HKLM\System\ndcucfg\Port=<COMx:>.

When trying the build this project in VS2008 I get this linker error
Error 3 error LNK2001: unresolved external symbol IID_IUnknown uafxcwd.lib RS232Test
and for 9 other IID symbols. I have tried to figure out what is missing or wrong but without any luck.
Can you help?Regards,

Hello,
the code of this sample is very simple. I assume that conversion to VS2008 fails. Create a new commanline project with VS2008 and compile it then copy the RS232Test code to your project and try to copile again. Does it work now?
