...found so far. 1. It's a Smart-UPS RT 3000 XL 2. The 940-0095B cable now uses an RJ45 connector at the UPS end. 3. It now requires a baud rate of 9600 instead of the 2400 used previously. Can anyone tell me if modifying drivers/apcsmart.c void upsdrv_initups(void) { char *cable; upsfd = ser_open(device_path); ser_set_speed(upsfd, device_path, B2400); to void upsdrv_initups(void) { char *cable; upsfd = ser_open(device_path); ser_set_speed(upsfd, device_path, B9600); all that is required in order to get nut to talk to it, or will other things need changing? Regards, Richard

...ta_agiler(). Hopping back-and-forth between various layers in the code is bad coding style as it makes the code difficult to understand. 2) So what is the benefit of this patch? It seem to try to optimize something away that complicates the subdrivers and really provides no runtime advantages (the ser_open() function is only run once). 3) Something you're probably not responsible for, but if flushing the input buffers is needed, this is something that should be done in main driver body (megatec.c). The driver doesn't flush I/O buffers, so the implementation of the Megatec protocol is apparen...

Dear Andreas, some googling revealed, you created a driver for the xanto series of online-usv.de. In what state it is currently? I've to manage a S2000 and would like to use nut for it, is it usable by now? Do you need another tester? TIA, Pete

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.
