[SunHELP] URGENT: TTL pulse on serial or parallel port

[Wolfgang Engelien]

Hi,

I would like to give out a ttl pulse
(length anything between 50-300 ms,
signal change from constant 0-5V to
any other value within 0-5V) on either
a serial port or the parallel port on
an Ultra2.

Does anybody have a hint on how to do this
or where to get information about this.

Thanks,
Wolfgang
