A Portmaster's ports can not be configured as async. The RS232 connectors do not even carry clocking. > can you think of any action we might take to overcome our problem? Stick KA9Q (with a 16550) on a pee cee and you'll be up in one day. Then sort it all out later with a better dose of planning. > In the longer term we may well need to move the end of our line nearer to > the centre of Lusaka.

A KA9Q like hack? But, if you are going to be forced to a central hub in the city center and spokes going out, do a small UNIX box running BSDI and a RisCom/8 serial card. In Conakry, I have one of those down by the international phone exchange, and 64KB spread spectrum radio links between sites. So, one has fixed cost high speed IP within the city, and a thin line out to international. randy
