Comm and VCSP port twiddling controls sigs

[DSMan195276]

In the original PC comm ports maxed at 4 physical ports.  Now the VCSP port could be a alternative to a 8250 comm chip.  Or even not a comm port but a Ethernet serial interface device.

What kind of hardware are you using, are you sure it gives you that level of control? I didn't think the 8250 or any of the other UART controllers allowed you to directly set/read those signals, rather only the parallel port gave that kind of control. If your hardware can't do it then the software aspect doesn't really matter.
