    make variable, eg "make DEFAULT_DEVICE=/dev/ttyUSB0"
  - atariserver: shorten labels in status line, display highspeed pokey divisor

2018-11-01:

    overlay files
  - atariserver: change options to select command line:
    use '-C' for CTS and '-D' for DSR
  - atarixfer: fix occasional errors with Happy 1050 drive
  - atarixfer: add support for 1050 Turbo mode with Linux serial drivers
    (requires strict SIO timing to be enabled)

    to "relaxed" mode. Strict timing on Linux drivers is needed to get
    1050 Turbo drives working with atarixfer.
  - atariserver: drop "highspeed with pauses" mode with kernel driver
    and make that available via "relaxed" SIO timing.
  - atariserver, atarixfer: add '-T s' option to select strict SIO timing
    and '-T r' to select relaxed SIO timing mode

  - atariserver: rename tape baudrate option from '-T' to '-B
  - atariserver: drop "tape emulation" key, CAS files can now be loaded
    via "load drive" option which start tape emulation mode
