Then you need an active device that shifts and boosts signal levels, a 
good deal closer to the machine in question.  A MAX232 equivalent in a 
box small enough to count as a plug casing would probably do it.

"Uncomfortable" should only rule out doing that for use cases at or 
below the urgency of "nice-to-have."

Or, to put it differently: if you can't even get there with a suitable 
plug attached to some thin-ish cable, that puts the situation beyond 
"uncomfortable," into the realm of "practically impossible to use."
