in the end i went with this for the router, using an IMD2A for the two transistors.
Personally I haven't used RS232 in ages, only different "TTL" serial variants of 5V or 3.3V.
yehh i have to be reaasonably compatible with RS232, as this is actually going to have a 9-pin header on it. although the only thing it will be connected to in most cases is one of those... yup, USB serial converters.
Why don't we include a USB to TTL-Serial chip on the card and/or carrier.
USB-to-TTL.... ah, because that would take out one of the 4 USB ports. in this "product" there's only 1 4-port hub.
