[DRE-maint] Bug#597526: libserialport-ruby1.8: get/set line state (cts/dtr) is broken

[Alexander Neumann]

Package: libserialport-ruby1.8
Version: 0.7.0-1
Severity: normal
Tags: upstream patch

Hi,

Reading the CTS and setting the DTR line state is broken:
$ irb1.8
irb(main):001:0> require 'serialport'
=> true
irb(main):002:0> s = SerialPort.new('/dev/ttyUSB0', 19200)
=> #<SerialPort:0xb74eaf7c>
irb(main):003:0> s.dtr = 0
irb: symbol lookup error: /usr/lib/ruby/1.8/i486-linux/serialport.so:
undefined symbol: set_signal
zsh: exit 127

$ irb1.8
irb(main):001:0> require 'serialport'
=> true
irb(main):002:0> s = SerialPort.new('/dev/ttyUSB0', 19200)
=> #<SerialPort:0xb74c8a30>
irb(main):003:0> s.cts
irb: symbol lookup error: /usr/lib/ruby/1.8/i486-linux/serialport.so:
undefined symbol: get_line_signals_helper
zsh: exit 127

The attached patch fixes this problem.  The version is very old, there is a
new upstream version (0.7.2) available:
http://github.com/toholio/ruby-serialport

And even a forked version 1.0.1 (since the original hasn't been modified since
2008) at http://github.com/toholio/ruby-serialport

If you need help, just contact me.  If you aren't interested in maintaining
this package any more, I would gladly take it over.

Cheers,
- Alexander
