speeds.sh

#!/bin/sh
#
# This file attempts to list all likely baud rates, and generates a header
# file containing them, along with conditionals to only include rates that
# are supported on the target system.
#
# Currently, this list is a merging of the speeds found the headr files
# Linux (kernel 4.11) and FreeBSD 11.0-RELEASE. (FreeBSD includes oddballs
# like 7200, 14400, 28800 & 76800, while lacking many of the higher speeds
# 500000, 576000, and everything from 1000000 upwards that are included in 
# the Linux headers.)
#
# The dterm command "speeds" will list the available speeds, i.e. the
# intersection of the set of speeds found in this file and those listed
# in the system header files. Note that this list is not the list of
# speeds supported by the actual hardware.
