data types through serial port

[amrhosam]

how can i find the data form i recieve from a serial port?
do i receive it in Hex? or binary? or ASCII?
a simple micrcontroller as a transmitter sends me 0x8F in hex for example..how am i gonna receive that data..?and how can i resolve it to read as a hex again?
i hope my question is clear enough..thanx to you all in advance?

Looks like you could use the SerialPort class to do most of the work for you:
