Not what would be called modern these days but I managed to run across two MicroVAX 3100 machines with DST32/DHT32 synchronous serial interfaces in them plus two V.24 and one each of V.35 and X.21 cables that will plug into them. With some help from the people here, I managed to get the machines talking to each other using a null modem between the two V.24 cables. I also have two nearly identical syncronous modems, one with a V.35 interface and another with an X.21 interface but I have not managed to get these to talk to each other, probably because they can't be configured to match any of the speeds the DST32/DHT32 interfaces can do. One of the MicroVAXes has since died (again) and I haven't got around to looking at it yet to see what is wrong this time. Regards, Peter Coghlan.
