Hi, Does anyone know of a way to manipulate the modem control lines from userland? SVR4 has termiox and friends but I can't see an equivalent for FreeBSD.
The reason I ask is I am trying to talk to an RS485 bus - it is half duplex and the protocol converter uses RTS to control the data direction. I have a kernel driver which handles this but it has it's limitations (eg takes over the port and boot up, only usable on certain devices). I'm going to make it a line discipline eventually, but this was a stepping stone.
