The LCD controller of the 3310 is a Philips PCD8544 connected to the GENSIO interface (the same interface the CCont is connected to) in a write-only way.
Two ports are used, a data port and a command port. Before writing you need to initiate an gensio transaction (same as CCont), and before each byte check if the Gensio Write status bit is set.
The official Philips data sheet for this device can be found here.

This site is the result of a great deal of assembly code reading, research, countless (mostly futile) searches for data sheets, cross-referencing and analysing. If you use this information in any way please mention wumpus <blacksphere@goliath.darktech.org> (and others in the credits section) in the credits of your program/document. And tell me :) If you have more information please contribute. If you just copy this, stick your name on it and call it yours I hope you get your genitals bitten off by a three headed monkey. Have a nice day.
