I was one of the beta testers this summer of the Metricom Ricochet2, 
a much faster version of their packet radio Internet service. It 
looks like a modem (connects to serial port), and smells like a modem 
(ATDT, etc), but it goes 250Kb/s, easily. On the Macintosh under 
MacOS, they just connected it to the serial port, and ran the port at 
230Kb/s, and I actually saw throughput to match.

For the PC laptoys, they were all handed a PCMCIA card of some sort 
with a very high speed serial port on it (apparently the default 
serial port hardware on laptoys sucks), and a driver for same. There 
is also some talk of a USB version of the modem (though I asked, I 
was unable to get a cable from Metricom to test that on the USB Macs 
I have at home).

The ability to run NetBSD serial ports at high rates with no data 
loss is in fact very valuable if we want to take advantage of devices 
such as this.

Ideally, we (NetBSD) should always be able to run all peripheral 
hardware at the limits of its performance...
