Async tunneling: serial port differences?

We're trying to tunnel RS-232 data across a small IP network to remotely monitor/control serial devices. The end devices require DCD to be held high from the router. Working with TAC, so far the AUX port doesn't seem to be able to do this, so we would have to disable flow control, which isn't a viable solution.

1) Do other serial interfaces have the ability to hold DCD high?

2) Any suggestions how to fake the AUX port?
