Binary Protocol

In non-PTY mode, binary messages are prefixed with a stream identifier byte. In PTY mode, binary data is sent raw without prefixes.

Binary Frame Format (non-PTY):
Stream ID (1 byte) + Payload (N bytes)
Stream ID Name Direction Description
0 stdin client → server Standard input data
1 stdout server → client Standard output data
2 stderr server → client Standard error data
3 exit server → client Exit code (payload is exit code as byte)
4 stdin_eof client → server End of stdin stream
