Thank you for the review Michael. @Rebecca Cran <mailto:rebecca@bsdio.com> , @Liming Gao <mailto:gaoliming@byosoft.com.cn>  have you had time to take a look at this? It is a fairly simple change, following the same logic as xdrlib with a few modifications to use some newer python functionality.

 

Thanks,

Joey
