[BC] Long serial connections

[Evan Elrod]

Hello,
Quick question...

What is the longest serial/com port run that will still work?
We just moved studios, and want to have our Sage Endec in studio, while
still having our Multi Station Relay back in the rack room.  (Pretty good
piece of ground to cover.)
I'm having trouble getting it to work at all now, and I'm wondering if the
distance could be to blame?

Any one have experience with long runs like this?

Thanks in advance,
Evan Elrod
