  From the Southern California OS/2 User Group:

An interview with Rick Curry, a professional OS/2 Device 
Driver programmer with years of experience writing a 
variety of OS/2 drivers and a specialist in SCSI/ASPI 
drivers, is now online at

    http://www.scoug.com/os24u/1998/scoug808.2.curry.html

In the interview, Rick touches on many subjects, including

  - how he programmed Las Vegas slot machines to come up 
    with combinations that pleased the state Gaming Boards
  - his OS/2 SCSI device driver subsystem for the 
    Burlington Northern Railroad's WORM drive jukeboxes
  - Warp Server's and LAN Server's ability to associate 
    several serial ports together as a "shared modem pool"
  - how Warp Server improves its performance by allowing 
    drivers to intercommunicate with IOCTL calls without 
    leaving ring 0
  - OS/2 drivers compared to NT drivers, NT's overhead, and 
    how much slower NT is
  - how ASPI (Advanced SCSI Programming Interface) works, 
    and how to get the documentation
  - how to decipher a Trap error and determine the cause, 
    and the utility he uses to do so
  - what "scatter/gather" is, why a driver must properly 
    process it, and why your old SCSI drivers may occasionally 
    give you Trap E errors
  - what compilers he uses and how he chooses the proper 
    one for a project
  - what you'll need to write your first driver, and a tip 
    for debugging your drivers
  - his OS/2 work for JPL on embedded systems
  - his work with OS/2 LADDR (Layered Application Device 
    Driver) drivers
  - his offline utility for the YARN newsreader which 
    creates a viewable "DejaNews"-style database of the news 
    you've downloaded
  - how he traces spammers

Included at the end of the interview is an extensive url 
list.

The author wishes to extend his thanks to Mr. Curry for 
taking the time to make this interview possible.
