RS232 / TCP converter and BSD.

They make line drivers to sit inline and boost the signals to extend the range, similar to T1 repeaters I suppose.  I had to use some 10'ish years ago. They weren't "too" expensive then, can't imagine the would be now.

But back to OP ?, I'm sure someone has a program that takes an RS-232 stream and sticks it in tcp or udp.  If I'm bored today I'll poke around the ports and google and such.

	I was wondering about that when I wrote my long-winded
response. I was confused and thought the maximum length for
RS-232 was longer than it is. 70 meters is almost 25% out of
range which is kind of pushing things.
