I've bought mine some years ago at two different normal hardware stores, it's a red/white box labelled "FUNKUHR fuer den PC". It contains a rectangular box with a red 5mm LED an a Green arrow/triangle printed on top and a DB9 RS232 cable, no manufacturer or brand available but i've seen exactly those devices sold by other manufacturers - dirt cheap. AFAIK, they output a 50 baud signal of the DCF77 data stream at the serial port which is the same everywhere for those types of devices so it should not matter what brand you buy als long as the principle is the same. FreeBSD's xntpd explicitly supports a "Boeder" clock, but the driver works for mine too (because of what i said earlier). My device gets it operating voltage of +12V and -12V from RTS and DTR and (i think) this is what the defaults are (before that i had to use comcontrol in rc.serial to set this). I use those devices for providing time to the network at home and at work without any noticable problems. hellmuth -- Hellmuth Michaelis hm@kts.org Hamburg, Europe We all live in a yellow subroutine, yellow subroutine, yellow subroutine ...
