Introduction

We continue to expand our product line as well as enhance the stalwarts we’ve had over the years. We continue to experiment with the Windows CE (Pocket PC) platform as it pertains to serial communication and hope to release a new product in the first quarter of 2003. We will keep you informed.

We continue to offer customizations on our COMM-DRV/NT, COMM-DRV/Lib, and COMM-DRV++ products. Please review our consulting services at http://www.wcscnet.com/services.htm.

Review the newsletter. We are sure you are bound to find one or more topics of interest.

USB to Serial Port Converter

 With the advent of laptops and desktops without built-in serial ports, many customers have been asking for USB to serial  port (RS232) converters. Well, we finally have one. The part number is HdwUSBRS232.  It is compatible with both COMM-DRV/Lib and COMM-DRV++. Please view the Special Offers section of this newsletter for time limited special pricing.

SI-Scope & SI-Comm Electronic Distribution

We are now distributing both SI-Scope and SI-COMM in electronic form as well. I am sure our international customers will welcome this as they can forego delays in shipping, customs, and high shipping costs.

The SI-Scope online documentation provide all the documentation necessary to build the cable yourself. To purchase either product electronically for immediate download, simply click on on the particular product's page.

MTask & Comm-Log Re-release

In the early nineties, WCSC released the last versions of the products MTASK and Comm-Log. Upon analyzing our website's logs , we found that there were hundreds of monthly queries for these products specifically and anecdotally for products of this type. As we mentioned in previous newsletters, MSDOS still has a stronghold in many embedded systems, and many other applications. In that light, we decided to re-release these products both electronically (complete online manuals) and/or with hardcopy manuals.

To purchase either product electronically for immediate download, simply click on on the particular product's page. Alternatively, you may use our standard shopping cart to purchase with a hardcopy manual.

Both products are offered at $29.95 and include their respective previously unreleased source code. The sources for MTASK provide a good exercise in understanding multitasking and steps needed to make MSDOS  preemptively multitaskable. The sources for COMM-LOG provide a good exercise in understanding a simple script interpreter.

No support is provided for these products, however full documentation and pertinent source code is included.

Tip Of The Month

Some COMM-DRV/Lib functions have the ability to block to wait for some event (presence of data, space in buffers, wait for ring).  These functions include GetPacket(), Dial(), ModemConnect(), etc.

If one needs to close the port or abort the above mentioned functions before they complete, it is necessary to have these functions abort. The basic solution to this problem is to install a callback function with CdrvSetTimeoutFunction() and have the callback function force an immediate timeout.

We created a very simple MFC application to illustrate one method for accomplishing the abortion. Download ForcedAbort.ZIP to view the example.
