Sounds like you want to put the line in termios "RAW" mode.

For instance, my application right now is essentially receiving from the console and sending the received message back out to the console. This works fine in console situations. For example, when I type “hello world”, I get the reply “hello world” back. However, if I send the console a hex based message, let’s say “0x90 eb 00 10 00 10”, I get some garbage back, such as “0x90 eb 50 54 50 5e”. I think it’s also waiting for an ASCII carriage return, because when I send it 0x0D (ASCII carriage return), I get some of the data I originally sent but with extra data mixed in. By the way, I’m using cutecom for these tests.
