Aah no. I'm not on about *length*, I'm on about *connections*.
As it happens, your /extensions/ should not exceed 100m anyway
because they do get bad (says that somewhere in an extension booklet
I have).
What I mean, is that if you plug lot of extensions into each other,
then there are more contact points on the line (where the little plug
plugs in).
And yes, serial extensions would no doubt cause problems. Its always
best to have the serial cable into the modem, as short as possible.
