Modem Processor Test Set (SEI)

Custom Linux Driver

During 2003-2004, Squires Engineering designed, coded, delivered and supported a custom Linux driver to interface with custom hardware for a local defense contractor.

This custom Linux driver had the following driver features:

Probe to detect hardware
Support for "read", "ioctl", "open", "release", and "poll" functions
"procmem" routine for diagnostic purposes
Support for multiple hardware devices
Interrupt routine
Loadable kernel module

The driver was approximately 1000 lines worth of C code.
