	Well, we've been successful over our agency's Consolidated Data
Network (a PSN) and local Tellabs/David muxes.

	Many PSN's and muxes allow for permanent or on-the-fly disabling
of XON/XOFF flow control. Our PSN's thusly configured are referred to as
"File Transfer" ports. Corrupting uucico to conform to your transport's
current configuration strikes me as bass-ackwards.
