[Someone was asking how you can hook up a second modem. One person replied
that you'd have to either re-write serial.device, or add a new driver.
In either case you have to worry about preferences and programs that hard
code the old name.]

Another suggestion:
Replace serial.device with serial.interface and serial.hardware. A call to
open serial.interface specifies a default device to use (such as
myterm.hardware). If it exists, great--use it. If not, default to serial.
hardware. A dummy serial.device would be added that opens serial.interface
specifying serial.hardware.
Add the ability to "alias" exec nodes, so that myterm.hardware could be
aliased to "ethernet.interface" or "uw5.interface" (5th channel of the
uw protocol), or something else.
 
Then supporting a new serial port is as simple as creating a mydev.hardware
(which wouldn't need to do much more than character I/O and uart i
initialization).
