Fred, Many thanks. I have a DSO112A so I was interested in what you are looking to do.

I think LVTTL is ~3.3V levels rather than the 5V levels of the Mega2560. Some level shifting will be needed/prudent. > The bit stream format for the serial interface is: 115200 baudrate, > 8 data bits, 1 stop bit, and no parity.

I have written some AmForth words which work for me at 9600 https://www.mostlymostly.uk/post/2019.02.01/ I have just quickly reconfigured them locally for 115200. Simple typing at a terminal seemed OK. Beyond that, how much data is sent by the DSO112A, how often, and what you want to do with it will matter, so it is difficult to know whether it would work well enough or not.
