This patch introduces a handful of new options, I mentioned earlier in: http://www.mail-archive.com/nut-upsdev at lists.alioth.debian.org/msg02088.html See the large commit message in the follow-up for the details and rationale. I realize it's a bit larger diff - so if it's required I can split it into few smaller ones. Michal Soltys (1): APC smart driver update and new features.

This is 2nd version of the earlier patch featuring a few new features and fixes to the apcsmart driver, following the remarks in: http://www.mail-archive.com/nut-upsdev at lists.alioth.debian.org/msg02294.html Major changes from v1: - handle battery.charge and battery.runtime checks at main.c level - handle "immutable but writable" conflict gracefully at driver level -

Hello all, For an upcoming project I will have to interface with a 24V DC UPS from Siemens (full name: Siemens SITOP UPS500S, manufacturer nr 6EP1933-2EC41). As this device is not listed in the compatibility list, I will have to write my own driver. I already found out, that the UPS has a serial-over-USB interface (USB full-speed, 12 MBps), using an FTDI chip. Over this serial port, it will

...no > more data left in the input buffer. So flushing the input buffers > was not guaranteed to work. This still holds true, a zero length reply doesn't mean there is nothing more in the input buffer (this might be an empty line with only a <NL> in it), so we'd better use ser_flush_in() or ser_flush_io() instead. Best regards, Arjen -- Please keep list traffic on the list

...don't recall any other drivers which parse a continuous stream of data without sending a query command. For a query/response example, ivtscd.c is relatively straightforward to understand. Given the fixed-length strings and unambiguity of the commands, you might want a loop like the following: ser_flush_in() while(!done && !timed_out) { ser_get_char() // append to buffer check for match check for timeout } One thing that may be useful while waiting for hardware is to embed a test harness in the code. We don't have much of a standard for this, but as long as the code doesn...

Hi Kirill, just to notify you that your al175 driver is being removed from the NUT tree, as of 2.4.0-pre1. if you wish to see it entering the tree again, please contact the Development mailing list to talk about it.
