Reading Packet Id from Byte

I have a packet that I need to send to a client with an ID of 255. I've had no problems sending packets with IDs of 0, 1, and 2. The ID has to be 255. For some reason, after the translation has happened, both me with my server, and the client, get "63" for any Id greater than 127.

This is the code I am using:

Console.WriteLine(Asc(System.Text.ASCIIEncoding.ASCII.GetString(System.Text.ASCIIEncoding.ASCII.GetBytes(Chr("255")))))

Now, This is an overly complicated version of what the serve开发者_开发百科r does. You may consider this a bit unnecessary but the inverse functions performed are for your viewing reasons only.

Where it says "255" is the Packet Id I need sent in the format above. As I said, anything larger than 127 returns "63". Very annoying.

Any help is appreciated.

Taken from here:

ASCIIEncoding corresponds to the Windows code page 20127. Because ASCII is a 7-bit encoding, ASCII characters are limited to the lowest 128 Unicode characters, from U+0000 to U+007F.

So you can't use that technique, because 255 is not a valid ASCII character.
