What is the difference between ～んとする and ～うとする?


I ran into ～んとする the other day and I think I get the hang of how it works and
what meaning it conveys, but it seems eerily similar to that of ～うとする.

I know Japanese have a lot of different ways to say the same thing, so I
wonder if there's no other difference apart from conjugation between these
two. In other words, I wonder if the following examples mean the same:

> 見る → 見らんとする  
>  見る → 見ようとする




  * 見んと (<見むと) is more literary/archaic and can be more bookish than 見ようと.  
(You don't say 見らんと)

  * 見んとする (<見むとする) *  consists of: み (未然形, imperfective form of 見る) + archaic volitional auxiliary ん (む) + particle と + verb する  
* You might also encounter an archaic verb す used instead of する , as in 見んとす.

  * 見ようとする consists of: み + volitional auxiliary よう + particle と + verb する 

A few examples:

> せんと, 送らんと, 書かんと, 言わんと... ← literary  
>  しようと, 送ろうと, 書こうと, 言おうと... ← modern
