Assuming the LCD uses the common SED1520 graphics controller, the command to config the LCD is

Config Graphlcd = 120 * 64sed , Dataport = Portc , Controlport = Portd , Cd = 2 , Rd = 1 , Ce = 3 , Ce2 = 4 , Reset = 0

You can set the Dataport and ControlPort to whatever you like, and the pins too. LCD CS1 is Ce, CS2 is Ce2.

Place the command
$lib "glcdSED122.lib"
somewhere after the $regfile statement in your code to pull in the graphics library.

Can you tell what Bascom compiler you are using, AVR or 8051 because you also asked this question in the Bascom 8051 section.
