Course OS2DD101 - OS/2 PDD Serial, Parallel Port Device Drivers

Objective

This five day workshop will enable programmers to write OS/2 Physical Device Drivers (PDD). A PDD enables I/O ports (serial, parallel, A/D, etc) to be shared by multiple OS/2 applications.

This workshop describes how the PDD communicates with the OS/2 kernel using the DevHlp interface. Installation and debug techniques will also be covered. The Developer Connection Device Driver Kit for OS/2 (Devcon-DDK) will be used extensively in order to build and test the PDD.

Length

5 Days

Target Audience

IBM or OEM programmers who code device drivers for PC hardware, such as serial, parallel, SCSI, or proprietary interfaces. This workshop is a recommended prerequisite for all other device driver workshops, except PM Printer and Video workshops. This course is recommended as a prerequisite for all other device-driver courses except two: OS2DD302 and OS2DD306.

Attendee prerequisites

  • Programming expertise: C and/or MASM
