   - You can control the PT unit by writing corresponding control bytes (see {{:help:common:aimotor701_manual_megarobot.pdf|manuál}}) to the file ''ser'' using command ''fwrite''.
-  - To simplify the PT control the following function is provided:<code>ptmove(ser, pan_pos, tilt_pos);</code> where ''pan_pos'' corresponds to the absolute rotation angle around vertical axis, ''tilt_pos'' corresponds to the absolute rotation angle around horizontal axis. Range of values for ''pan_pos'' and ''tilt_pos'' is from 0 to 254. I covers approximately 80 degrees in a given direction. To set the unit into the initial position (i.e. the position camera optical axis is perpendicular to LCD screen) use the following values ''pan_pos==127'', ''tilt_pos==127''.<code>function ptmove(ser, pan_pos, tilt_pos, speed)
