[dts] [PATCH] bug fix: fix issue when DTS run on Fedora21 and freebsd

[Liu, Yong]

Hi Xiaonan,
	Function send_expect_base is one of the basic functions in DTS framework. So we should not just move back and work around this issue.
	This issue should be investigated and fixed. You can look into it and help us get to know the root cause of why ret_status is not int.

Thanks,
Marvin
