+/*
+ * <termios.h> for the MontaukOS git port.
+ *
+ * compat/terminal.c uses tcgetattr/tcsetattr to turn off echo while reading a
+ * passphrase, and to put the terminal in raw mode for single-keystroke reads
+ * ("git add -p"). The MontaukOS terminal has no line discipline to configure:
+ * the libc reads stdin through SYS_GETCHAR and does its own echoing.
+ *
+ * These calls therefore succeed and do nothing rather than failing, because
+ * git treats a tcgetattr() failure as "not a terminal" and a tcsetattr()
+ * failure as fatal in some paths. The visible consequence is that a typed
+ * passphrase is echoed -- there is no credential helper in this port, so
+ * nothing prompts for one yet.
+ *
+ * Implementation in montauk-compat.c.
