Hi,

We are using .NET Compact framework and we want to use UART D for communication with our device. When we do a port scan in .NET Compact Framework we do not get COM4 as available port. How can we fix this?

Hi,

By default UARTD on Vybrid moduels is disabled. To enable it please add this registry entries.

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\UARTD]
    "Order"=dword:1
    "Dll"="vybrid_serial.dll"
    "Prefix"="COM"
    "Index"=dword:4
    "DeviceArrayIndex"=dword:3
    "TXPIN"=dword:23
    "TXAF"=dword:6
    "RXPIN"=dword:31
    "RXAF"=dword:6

Please note that UARTD does not support RTS/CTS
