[Serusers] where is the remove_hf function?

[Dale J. Robertson]

I used and tested the remove_hf function in ser 8.14 on a test box 
running netbsd. After confirming that it operated to my satisfaction, I  
loaded the latest package on my soekris single board i386 computer 
running openbsd 3.7. When ser started up  and parsed my config, It 
complained that it couldn't  find the remove_hf function.  Was this 
function removed from  ser  9.4? or has it been  relocated to an 
external module.
Thanks,
Dale
