#138736 - tghere is no such thing as 2 stop bits
Responding to: ???'s previous message
however, there is 'holding the line for a while'

a stop bit is not really a bit it is 'idle line' (high) with a duration of minumum 1 bit time.

to achieve "2 stop bits" all you have to do is to delay sending the next vcharacter.

no bit-banging or such needed

what I would do:

at TI start a timer for one bit time or whatever more you want

when the timer interrupts, stop it and send the next char

this will loop nicely
