Doug,
I get the feeling EMC2 is on the cusp of full acceptance in the
control world. It is amazingly close to the capability needed to
compete with the old line commercial controls. It is just as capable
and just as flexible. I only hesitate to claim it is more capable and
flexible because with

I'm quoting a message from an EMC user to see if anyone else has seen
any signs of this problem.

Alex,
Thank you for your work. This is an awesome feature!

Perhaps the intent of my remarks were misunderstood, or
at least buried by others concerns.
My point was that a casual visitor to the web site would
have no idea that the map or forums even existed.
For me at least, it is not possible to see any of the above

I think the hal syntax is a pretty neat way to wire up a directed
acyclic graph.
I've played with graph programming for a very long time and here is
another syntax that, one day, we may want to think about:
value= function( input1, input2, ..., inputN )
more_output = another_function( value, 5 )

probe_parport enables "ISA PNP" parallel ports which are not assigned
an I/O address by the BIOS. probe_parport is expected to have no effect
for PCI parports. Some on-board parports behave like "ISA PNP" ports,
though.

HAL knows what can accept input and what can accept output and does what it
needs to do automatically and will error
As a new guy, I start my study of the HAL literature.
Noting my questions, I thought to burden the group in a feeble jesture of
participation ;-)
this example quizzes me:
To connect a signal to a pin we use the net command.

I hacked the map some more, and now the markers should only be visible to
registered users.
So if you're not signed in, you can't see any data (except the data we
publish, like the EMC Fest location for this year).
We can also add other markers (NAMES maybe? or any other emc events..).

Also when driving highly inductive loads you want to start triggering at
voltage maximum and then inject a shower of pulses into the gate for maybe
45 degrees. Otherwise the SCR/Triac main current might not have risen enough
at the end of the first trigger pulse to sustain conduction. If we try wit

Thanks Chris,
exactly on target, this one IS based on MOSCHIP MCS9805CV. Have to go find
something else.

If your card is NETMOS based, they are known not to work in EPP mode.

Trying to make my EPP communication work today, works OK on builtin 0x378

That PCI card is OK with hal_parport (using SPP only at 0xBC00) so I started

Hello Kirk,
small power applications such as dimmers must switch on the Triac at any
time of the AC cycle. This produced a high current surge if it is near the
peak of the sine and thus a lot of EM noise on the cables.
High power appliances such as furnaces etc. turn on at the zero crossing
