How does one control the UART ports directly on a SS1

[Troy Schumaker]

Would anyone know how to directly control the UART on a SPARCstation 1?  I
would like to be able to control DTR (e.g. toggling this port) along with
other ports on the UART.

I recognize that this is a very, very old fashioned way to approaching
things, however we are under a specification for a client, requiring us to
demonstrate this capability.

Thank you for your efforts.
