Oops. that is 0x55 0x55 0x55 0x00 -- 4 bytes total

Krzysztof,

Do you have the capability of reading voltages in the adapter? I've been looking at the Pascal code and there are calls to undocumented libraries.

Specifically, is RTS (pin 4 in 25pin adapter or pin 7 in 9pin adapter) normally high or low?

If you also have an oscilloscope, I'd be interested in timings during the toggle phase. There is a call to Sleep(10) that could be msec or usec. He also seems to send 0x55 0x55 0x55 0x55 0x00 to generate 16 pulses. I see 4 pulses per 0x55 byte and perhaps one more for the stop bit, but it would be nice to confirm. I guess we'd see 15 regular pulses (~16usec each) and a gap before the 16th. Vcc or RTS could be the trigger.

Thanks,

Paul Alfille

that is funny (maybe it is not, I will compare shematics later,
http://www.elektroda.net/dla_kompa/ds1820/ds9097e.gif looks similar) but that
interface DOES work with 32bit timex API!

I did that adaptor like Lenoid wanted and it works with _his_ program and
ds1821.

Then I have disconnected 1821 and put 1820 in the place, and Timex viewer does
show that device! I did not test any other DS**** that I own.

I will check owfs later and post my results here. In the past you told me that
simple http://www.elektroda.net/dla_kompa/ds1820/ds9097e.gif adaptors simply
does not work with owfs, or I have a memory hole in my brain?
