Sending hex values arduino serial monitor

I am running some code that only accepts hex values. Is it possible to configure Arduino's built-in serial monitor so it is able to send commands such as this- 0x5A 0x08 0x80- to initiate certain functions?

If not, do you know of a program that would allow me to send hex values to a Serial port?

Thanks in advance.

Most terminal programs can, if I'm not mistaken.

You can also send it as text and convert at the Arduino side to numbers.

Remember, hex is only a text representation of a number.

Might be easier to modify the code to accept other types of input. Post the code, using code tags.
