100ms is an awful lot of 'inverter gates'!
===========================

You mis-understand - the inverter is simply to alter the negative-going logic to positive-going, not to delay!

I had the same issue with my Sure Electronics board:

and used a spare inverter on the board.

BTW: I've used boards like the Adafruit one to talk directly to the serial port on an older Dell PC (RX and DCD only) without the need for level translators. It was a direct connection (few centimetres) without a long intervening cable run, though.

Cheers,
David
