Duplicate 0xFF in Socket.Receive(Byte[])???

I use Socket.Receive(Byte[]) to receive data in server from client over
TCP/IP. All byte values of 0xFF sent by client are showing up DUPLICATED in
server receive. In other words, if client sends [0xFF, 0x01], then server
receives [0xFF, 0xFF, 0x01]. It's as if bytes having values 0xFF are treated
as some sort of DLE that needs to be repeated to get through. Any idea what's
going on here?

I am confident that's not actually the case.

Not without a concise-but-complete code sample that reliably demonstrates
the problem. Note that for network problems, that means both ends of the
communication.

Undoubtedly you have an error either in your sending code or your
receiving code. But what that error is would be impossible to say without
a code example demonstrating the problem.

Turns out a serial to IP bridge device in the loop was performing telnet
translation.
