SerialPort1.Write(...) is not sending the right value...

[dtvonly]

Hi. I am using SerialPort1.Write(x) in VB.Net (express Visual Studio 2010) to send the value x to an MCU.
All "communication" are correct; i.e. RX and TX and interrupt from MCU are all working fine.

There is only one issue:

dim value as integer
value = 45
SerialPort1.Write(value)

The MCU side is reading 52. What is wrong? Please advise.

p.s. I had also tried SerialPort1.Write(val(value)) but this does the same thing.

By using Write(String) method you're sending the String value "45". Ascii value of char "4" is decimal value 52.
