How can I convert an ASCII string of variable length to a HEX number?

[žabić]

Hello,

I read data from the serial port 5 times in a second (while loop) and the number of bytes read varies every time.

The data comes in as ASCII string, and I can see the HEX representation if I connect a HEX string indicator, but I need to permanently convert data to a HEX number. 

How can that be done?

TNX! But what will happen if i get 00 in the middle of the hex string. Will that be left out?

No, if the string contains a NULL byte (0x00) then the output string will show 00.
