Re: seems to be an intel's problem

it seems it's not Visor's fault after all, according to a post I've just found on intel's support messageboard, some of their switches works just with a nullmodem cable "with all the pins wired".
but the best (or the worst) is that at intel's support have not the slightest idea about why or on wich device it happens.
and, BTW, what the heck "all the pins wired" means
"all the pins wired" does not make sense in the context of a null modem cable.
There are two types of null modems:
1) A "full handshake" version that not only crosses the transmitt and receive pair, but also crosses all the handshaking and flow control signals also.
2) A "no handshake" version that crosses the transmitt and receive pair, but does not connect the hanshaking or flow control lines between the two devices. Instead it simply feed the output handshake lines from each device back into the input handshake lines for the same device. This way both devices think the other one is "always ready". This is likely the kind of null modem that you want to use with your Visor.
The term "all pins wired" is usually used for serial extension cables which are described like "all pins wired straight through". Null modems are never wired straight through by definition.
