gm4lin is a Linux driver for the serial port GM-45 and GM-10 radiation detectors. The driver is able to handle virtually any number of detectors connected to a single computer and to log data to the screen, to ASCI files or to a MySQL database (local or remote). Average activity and pulse mode with a fake RC decay are available in order to come as close as possible to common analog radiations detectors. This is console-only software.
