Try if commenting out lines

241	ser_set_dtr(upsfd, 1);
242	ser_set_rts(upsfd, 0);

in 'ivtscd.c' makes any difference. I added these because many serial  
interfaces on UPS devices require this, but this may have backfired on  
us. It's probably not needed anyway, since there seems to be no  
isolation in the SCD anyway (so we don't have to power the isolated  
parts through the serial interface).
