I deleted my free trial by mistake and now can't re-install it. Is there a way to just install the ComDebug program? That's all I want to try.
ComDebug, the data logging and COM port trouble-shooting software costs our subscribers nothing and never expires. It works with devices which communicate over RS232, RS422, RS485, Modbus and TCP/IP. You can download a copy of ComDebug on its own from https://www.windmill.co.uk/serial.html
"Your software works great; it's the only package that allows me to set the DTR line low...required by the TI (Texas Instruments) development board configuration."
"Really useful tool. We have been using it to get familiar with quite a huge set of devices."
"Outstanding little tool! Best freebie I've ever seen!"
A reader this month wanted to know how to add average, maximum and minimum horizontal lines to his Excel chart.
- In the headings row of your spreadsheet type Average, Maximum and Minimum into the three columns to the right of the data.
- In the first data row, use =Average, =Max and =Min to calculate the average, maximum and minimum values for the data.
- Scroll down to the last data row and do the same.
- Draw your line chart as normal.
- Make sure Excel interpolates the empty cells - drawing a line between points. For older versions of Excel, from the Tools menu select Options and Chart and choose to plot empty cells as interpolated. For later versions right click the chart, choose Select Data then "Connect Data Points with Line" in the Hidden and Empty Cells setting.

Sonic cyber attack shows security holes in accelerometer sensors
Sound waves could be used to hack into critical sensors in a broad array of technologies including automobiles, medical devices and the Internet of Things. The new work calls into question the longstanding computer science tenet that software can automatically trust hardware sensors, which feed autonomous systems with fundamental data they need to make decisions.

Quantum Computers May Have Higher Speed Limits Than Thought
How fast will a quantum computer be able to calculate? While fully functional versions of these long-sought technological marvels have yet to be built, one theorist at the National Institute of Standards and Technology has shown that, if they can be realised, there may be fewer limits to their speed than previously put forth.
