Revision: 1.1
Committed: 2002-07-31T16:46:14Z (22 years, 3 months ago) by cebix
Content type: text/plain
Branch: MAIN
CVS Tags: nigel-build-19, nigel-build-12, nigel-build-13, nigel-build-16, nigel-build-17, nigel-build-15, HEAD
Log Message:
- it is now possible to make the serial drivers pipe their input/output
  to programs by using a '|' followed by a command line as the modem or
  printer port setting (instead of a device name like '/dev/ttyS0')
  [Brian Johnson]
- the option "--config FILE" tells B2 to use a different config file
