Articles


 

Over the years Stuart Baker has published many computer related articles. This page serves as an index to these articles. The articles are listed in chronological order to allow easy access to continued subjects. Since computers technology evolves very rapidly, and some of these articles date back more than 10 years, some of the topics will have only historical interest. This index also contains articles of interest that were not authored by Stuart Baker. For quick access go to the Other Contributions section.

  • A Glimpse Into the Not-Too-Distant Future - (1984) Describes the changes that were made to BIOC and MTM to support a full screen editor. The BIOC driver was enhanced to support type-ahead and a new read request called a monitor read. MTM was modified to support the new commands ENABLE TYPEAHEAD and PREVENT TYPEAHEAD.
  • The Insidious Interaction of VFC and IMAGE Writes - (1987) Describes the interaction between VFC (Vertical Forms Control) and Image writes. This topic is of particular interest to users of FORTRAN.
  • Vertical Forms Control - Revisited - (1987) Describes in detail how the BIOC driver handles VFC writes.
  • How compatible the MPC - (1987) Takes a close look at the 8-line communications multiplexer aspect of the new Multiperipheral Controller (MPC). It compares the standard 8-line communications multiplexer with the RS-232C support of the MPC.
  • When the Dust Settles - (1987) Addresses the lack of approved standards and compatibility among the new breed of 9600 bps modems. The CCITT V.32 standard is being developed to address 9600 bps full-duplex communications and error correcting. Until a standard is approved, the industry has no direction.
  • The Pitfalls of Progress - (1988) Outlines the problems in getting a Hayes V-series Smartmodem 9600 modem to function on an OS/32 system.
  • XMODEM and High Speed Modems - (1988) Explores the throughput problem of XMODEM file transfer with this new breed of modem like the Hayes V-series 9600.
  • CTD - The final solution? - (1989) Addresses the development of the OS/32 CTD (Common Terminal Driver) driver. The intent of CTD is to develop one driver that addresses the needs of RELIANCE and MTM users.
  • CTD - New Flexibility Arrives Soon - (1989) Is a second article about the OS/32 CTD driver.
  • BIOC Upload/Download - (1989) Describes the OS/32 BIOC Upload Download feature and the procedures used to tailor the BIOC driver from an application program.
  • BIOC Ctrl-W & Ctrl-X Updates - (1990) Describes an update I developed for the OS/32 BIOC driver. Yes, once again I am making changes to BIOC. I guess it is difficult to totally ignore a past love.
  • CTD - A Hands On Report - (1990) Describes my hands on experience with the OS/32 CTD driver. I have been putting this discussion off for some time, hoping that the R08-03.1 update would resolve the problems I reported during the OS/32 BETA test. I finally found time to look at the CTD update. CTD has improved, but regrettably there are still problems. Here is my evaluation of the CTD driver.
  • Using OS/32's Wildcards - (1990) Outlines one approach you could use to implement wildcard file handling in the OS/32 R08-03 environment.
  • Kermit and Xmodem - A Comparison - (1991) Compares the Kermit and Xmodem file transfer protocols.
  • The Dust Has Finally Settled - (1991) Is a follow-up to When the Dust Settles. At that time I did not recommend choosing these high speed modems unless you could pay back your investment within one year. Well a lot has changed in 3 years.
  • SDECM - A Brief Overview - (1991) Describes SDECM, an OS/32 monitor that has served BIOC and ITAM users well for many years. SDECM is an acronym that stands for the San Diego Environment Control Monitor. It is an extension to the ECM program that is included in the OS/32 Reliance package. It provides the same basic functionality as the original ECM, but it also handles terminal pairs) Inbound and outbound dial lines, and supports automatic screen save and disconnect for dial lines.
  • What are Network Redirectors? - (1991) Introduces the topic of PC DOS based network redirectors that use INT 14 to perform serial port emulation over an SPX/IPX network.
  • How well do Network Redirectors Perform? - (1992) Addresses the topic of PC DOS based network redirector performance.
  • LIMS 244 Driver - What are its benefits? - (1992) Introduces the new OS/32 LIMS 244 driver. This new driver fixes all known problems with the 244 driver. Not only does this driver bring new functionality to your LIMS software, but you now have all of the BIOC features available at MTM without the need to switch drivers.
  • Ringing Lines - The Sneak Thief of Power - (1992) Addresses an insidious problem that could be robing your OS/32 system of precious computer power without your even being aware of it! At this very moment your asynchronous lines could be bombarding your system with interrupts, and if you have a 3280, you don't even have a wait light to give you any hint of trouble!
  • Network Redirectors Revisited - (1992) Addresses the topic of PC DOS based network redirectors that use INT 14 to perform serial port emulation over an SPX/IPX network. It specifically addresses how PC-Passport works with the CrossConnect network redirector.
  • Serial Communications Using a PC - (1993) Addresses the advantages of the 16550 buffered UART when used on IBM PCs and compatibles.
  • The Mouse has a Home in MTM and Reliance - (1993) Addressees the benefits gained by adding mouse support to a PC based 6312 terminal emulator. Mouse support may not bring OS/32 up to GUI standards, but it is sure a giant step forward.
  • OS/32 & Series 3200 SIG #1 - (1994) The first in a series of OS/32 SIG chair articles.
  • OS/32 & Series 3200 SIG #2 - (1995) The second in a series of OS/32 SIG chair articles.
  • OS/32 & Series 3200 SIG #3 - (1995) The third in a series of OS/32 SIG chair articles.
  • OS/32 & Series 3200 SIG #4 - (1996) The fourth in a series of OS/32 SIG chair articles.
  • OS/32 & Series 3200 SIG #5 - (1996) The fifth in a series of OS/32 SIG chair articles.
  • OS/32 & Series 3200 SIG #6 - (1996) The sixth in a series of OS/32 SIG chair articles.
