IVT SCD support status
Rainer, Arjen
I was wandering around the code, and found that few things are missing
around the IVT code:
- no manpage,
- no entry in driver.list
- no device{mfr,model,type} in the code.
I was about to submit a patch to address the above (ready to commit), but
wanted first to get an update on the status. looking at the last thread,
it's a bit unclear... I'm also interested an upsc output...

driver for IVT SCD solar controller ?
hi,
I'm using the SCD-20 solar controller from IVT Gmbh in combination with a
230Ah battery and a photovoltaic panel to power a small server based on an
Intel ATOM N270 CPU.
the controller is (will be) connected to the server via RS232 (1200 8n1)
and works like this:
- if the battery voltage drops below 12V, a warning LED is switched on
- if the...

In the native case, only dispatch_illegal_op_fault had to be moved.

IVT SCD serial port help
guys,
A bit off topic here, but since this issue already has a history here:
serial connection to the SCD, the never ending story ...
- the intel D945GSEJT mainboard (ICH7) has two serial ports with
onboard connectors which require a ribon cable to the external DB9
connectors in the case. I tested 5 cables, but none works. whereas I'm
not sure if it is a cable problem. this is what dmesg

Not sure why R_has_methods_attached() exists. Maybe Martin could shed
some light on that.

Long equation in documentation
...Here's the formula:
\deqn{Cov(r_{ist}, r_{iuv})= [.5\rho_{ist}\rho_{iuv}(\rho_{isu}^2 + \rho_{isv}^2 + \rho_{itu}^2 + \rho_{itv}^2) + \rho_{isu}\rho_{itv}+ \rho_{isv}\rho_{itu}-(\rho_{ist}\rho_{isu}\rho_{isv} + \rho_{its}\rho_{itu}\rho_{itv}) + \rho_{ius}\rho_{iut}\rho_{iuv} + \rho_{ivs}\rho_{ivt}\rho_{ivu}]/n_i}
How can I break the formula and optionally indent the second lower piece; though I'd settle for break it right now?
