As far as I am aware, it is not possible to use hardware flow control (RTS-CTS, DTR,
or any other signal) on a serial port card under AIX 2.2.  Does anyone know of a
driver that supports the use of hardware flow control on a 4 port serial card?
Actually, any pointers in the right direction would be appreciated.  One of the
desired applications is using Telebit modems at high speed, but I get funny results
when I lock the interface at high speed then rely on X-ON/X-OFF to throttle down to
a 2400 baud connection.  A second problem with the X-ON/X-OFF is that sometimes the
system stops honoring it.  The biggest difficulties come when using a port defined as
a printer but not using qdaemon to drive the port.

Any pointers to a solution are appreciated.
