Sending and recieving strings over ethernet (VISA/TCP/IP)

Appologies if this was answered elseware..

I am trying to connect to a device on my LAN and read/write string (write commands) to it via either the VISA VIs or the TCP VIs. I am not sure which is best. I am able to ping the device on the network at IP 192.168.2.10 and I was told by a co-worker that the communicaiton port for the device is "port 23".

My question is which is the better VI for this string comm (EX: get/set_frequency XXXX) and also how do I configure the VIs for said purpose?

I did not find the help within LV clear and I was having a hard time Googling my question.

Thanks
