interfacing with serial monitor (hterm)

i am a novice in arduino programming and simply want to display an analog value on my computer display. It works with the arduinos built in serial monitor but I can´t clear the screen to have just one value displayed.
If I use other monitor programms (like hterm) I do not know how to send the escape sequences for clearscreen and so on.
I would be thankful for any suggestions.

You need to decide what terminal emulation you want (say VT52/VT100), then send the appropriate control sequences as strings.

There might be better lists…
Erase screen is [2J

Well, HTERM might not have any generic emulations … but it is programmable
