I have LinuxCNC with the parallel port configured to create 1kHz on PIN14 and

board was only $11.23 Cdn and works best with a max of 1kHz. Any higher and

I think that you will have trouble with a 1kHz servo thread and a 1kHz PWM.
That doesn't work for
setp hm2_7i92.0.pwmgen.00.pwm-freq 1000.0
How do I set the PWM frequency? Googling hm2_7i92 doesn't turn up anything
that is helpful.
The generic docs for Mesa card HAL is here:
http://linuxcnc.org/docs/2.7/html/man/man9/hostmot2.9.html#pwmgen
But to find that you do need to know that the Mesa firmware is called
Hostmot2, and that the docs section exists.
It should be setp hm2_7i92.0.pwmgen.00.pwm-frequency 1000.0

You dont need to guess about pin and parameter names.
With LinuxCNC running type:
halcmd show pin hm*
to show all Hostmot2 hardware pins
and
halcmd show param hm2*
to show all Hostmot2 hardware parameters
To create a list of all pins, parameters, and signals as a copy-paste donor
file:
halcmd show all > linuxcnc-names.txt
