After a long time of lurking and looking through solutions like USB,

buy a scraped terminal server allowing me to connect up to 40
traditionnal 9600 serial devices as well as 57600 bps modems (slip and ppp
can be provided by the termserver). It's dirt cheap when gaming with
sensors and actuators, and wiring is build around standard ethernet cables
with RJ45. But ethernet and IP compatibility with OpenBSD is total, and i
can totaly rely on the code already wrote by people hanging around this
list.
could you precise some references to buy similar one ?
type "terminal server" into ebay. lots of options (old decservers,
cisco 2509/2511/2511RJ, lantronix, xylogic annex, livingstone/lucent
portmaster etc).
you might need to do some research, they won't always come with
everything you need to actually use them (in some cases: AUI/10baseT
transceivers, proprietary cables, flashcards, more RAM).
I won't able to do a better answer. But for your reference i use an old
Xyplex Maxserver 1640 in tftpboot configuration.
The whole doc and the firmware can be reached on internet. Note : In
spite of its higher port number, the 1640 price is often lower than
1608/1616/1620 price due to its lower max bps (57600 instead of 115200),
and sometimes it may be bough for quite nothing. There may be other
brand and model affected by the same offer/demand effect.
Good luck,
Eric.
