How to I send G-Code File through serial?

So I want to connect my Ramps1.4 Board to my pc and manually send it G-Code.

Instead of using Pronterface or other programs, I'd like to send it myself.
So far I've been using pyserial. I could send individual lines through the serial port, but thats not the ideal.

Ideally I'd like to send many lines of G-Code (or even a whole file). How do I do that?

Cheers

... I'm mostly using teraterm for sending multiline-macros or files per serial ... or, if reading/reacting to handshake too, write my own "senders" with VisualBasic or Python ...

Hi, thanks for the quick reply.

Maybe I've not been very clear... My problem is that Marlin only reads G-Code commands in the serial.

But I want to send more complex data to the board through the serial. How do I programm Marlin to recieve that?

Ideally I would like to have a classic Arduino-style Serial.read() where I send data to Ramps1.4.
How would I implement such a thing in Marlin?

... if the capability of common G-codes (and M-codes) arent sufficient, then you have to write your own firmware.

By the way - I'm controlling big industrial ultrasonic cleaners with up to 5 vats (+ load and remove zones) and moving ranges with up to 4 meters horizontal and 500mm vertical with a "standard" Marlin4Due (same as Marlin, but config/setup for ArduinoDue) ...

Do you have any experience with adapting the Marlin Firmware?
My problem is that the code is difficult to understand.

... I've modified some parts of Marlin4Due for my needs and to "expand" the communication to/from Pronterface ... and added some new M-codes too.

But this was "2 dayjobs back", so actually no time or interest to dive into again

Okay can one of your collegues help me with this then...?

... best bet could be to wait, if others will come by -- my colleagues are either in different themes ... or maybe even more busy than me for actual reasons
