ttyPos Driver for PAX Bank

A Linux kernel driver for PAX bank that creates a TTY interface for communication. This version has been modified to work with Linux kernel 6.6

Credits

This driver is based on the work of @alex-eri's ttypos driver. Special thanks for the original implementation that made this adaptation possible.

Version numbering (1.0.1) is arbitrary and represents only the current adaptation for kernel 6.6 compatibility.

Features

• USB to TTY interface for PAX PinPads
• Compatible with Linux kernel 6.6
• Supports bulk transfer mode
• Automatic device detection and initialization
• Thread-safe communication

Installation

Building locally is the recommended method for installation

Building Locally

cd src
make all
sudo make install

Creating Debian/Ubuntu Package

apt install build-essential dkms debhelper
dpkg-buildpackage

Usage

After installation, the driver will create TTY devices for connected PAX at:

/dev/ttyPOS0
/dev/ttyPOS1
...

Requirements

• Linux kernel 6
• Build essentials (gcc, make)
• Linux kernel headers
