The cursor blinking is off by default in Neovim and I want it back. I have tried to apply different arguments to guicursor, but didn't succeed. Since I want it to blink the same way in every mode, I think, I need something with the letter 'a' in it.

Here's what I have tried so far:  

`:set guicursor=a:blinkwait700-blinkon400-blinkoff250` (I also tried with 'i')  

`:set guicursor=a:blinkon100` (as the opposite of a:blinkon0 which switches it off)

I've already looked into the help but it didn't help me unfortunately.

**Update:**

What is peculiar is that `:set guicursor=a:blinkon100` enables the blinking in gVim, but not in Neovim.
