Serial instruments communication with cFP 2120

Dear all,
I'm new in the NI forums and here's my firts question.

I'm have a LIDAR sensor and I want to use it with my new cFP 2120. Communication is done writing and reading specific telegrams to the RS-232 port. Firstly I used old serial VIs and it works. What I'd like to know if it's worth to move to new VISA vi, specifically, do they decrease response waiting time at serial port?

Could anyone help me? I'd appreciate it!

Àlex
