External clock for P-I serial port?

[Chris Anderson]

Is it possible to provide an external clock for either or both of the
serial ports on the personal Iris? 

The manuals indicate that ioctl can set an external clock mode,
but the signal is undocumented. Is the clock signal a spare pin on the 
D connector, and if so, what should drive it?

Thanks for any info.
