Sending letters to Arduino to set time on a RTC

I’m doing a project making a clock using a Arduino and Nextion display in the Arduino I have code to set the time on a RTC by using serial monitor then using upper and lower case letters from the keyboard “H” is hours up and “h” for hours down I have buttons on the Nextion for these functions but how do I send these letters like the keyboard? Thanks for any help
