    A signal from a PC

    There is some way to avoid the "dead time" due to the "attempting close" message ?

    A signal from a PC

    Yes, here i post a drawing of the simple circuit i have assembled. The purpose is to supply a square wave or other signal, time controlled (with very long on /off duty cycle), to a simple counter (the DUT) that i need to test in these conditions. I apologize for the hand written drawing, i do it...

    A signal from a PC

    Hello Dr_Doggy, i am courius about the function of the portdelay option. How it works and how influences the DTR/RTS output ?

    Using the following command: C:\>serial_ringer port=com12 loop=0 on=200 off=200 portdelay=0 Attempting the opening of port: com12 switching on for MilliSeconds: 200 at: 27/11/2016 19:53:24 switching off for MilliSeconds: 200 at: 27/11/2016 19:53:24 switching on for MilliSeconds: 200 at...

    Sorry for the mistake. loop="whatever number" works in Win7 and 10.

    A signal from a PC

    Many thanks Dr_Doggy now it works with parameters on and off but is not using the n= param. It works forever, without look at the n value. I tested it in MS Win7-Pro and MS Win10-Home (both 64bit).

    A signal from a PC

    After some time, i try to connect a relay with a BJT to the serial port, i used again the program, using Windows7 but now it works only without the on off arguments: C:\Prove\publish>serial_ringer.exe on=3000 off=3000 baud=9600 port=com9 Eccezione non gestita: System.FormatException: Formato...

    A signal from a PC

    It works. Now i need to buy a NPN transistor and some components to drive a bistable relay to get the desired function, using your program in a batch DOS script. This should be a simple job i should be able to do. I need a few time and let you know. VisualStudio 2012 express seems a great tool...

    A signal from a PC

    I much appreciate your work. About the "n=x" option i mean something liker this: C:\publish>Serial_Ringer.exe on=5000 off=5000 baud=9600 port=com6 n=1 Attempting the opening of port: com6 switching on for MilliSeconds: 5000 switching off for MilliSeconds: 5000 exit here. C:\publish>

    A signal from a PC

    Sorry for the delay, i executed the command: Serial_Ringer.exe on=5000 off=5000 baud=9600 port=com6 on the directory where i placed the .exe and it works as you stated: C:\publish>Serial_Ringer.exe on=5000 off=5000 baud=9600 port=com6 Attempting the opening of port: com6 switching on for...

    A signal from a PC

    For my tests, i'd like do drive ON the RTS (or DTR) for n seconds and OFF for m seconds. If this is not possible, or too complex, a pulse of some seconds with RTS ON should be ebough.

    A signal from a PC

    Hello Dr_Doggy i take in consideration your suggestion about VS for the time when I will begin to study programming. About the Belkin Wemo, it is interesting but not suited for the kind of switch i need now: something like this: **broken link removed** But i still need to get a RTS (or DTR)...

    A signal from a PC

    After some tests, i decided that the Task scheduler of Windows is not a reliable tool . Crontab, in the Linux environment is a complete different story: robust and reliable. But i need to use MS Windows. So i try the DOS "mode" command, to manage the DTR and RTS control signals of my serial...

    Thank You Ron, this is not a little program: is a great program! Very useful for me.

    A signal from a PC

    Thank you all, after some googling, i find the Windows CLI command: mode comx rts={on|off|hs|tg} that should set the RTS "Request to Send" control circuit, on, off, handshake or toggle. The last two options are not well explained. The command works only if the PC has a native serial port or...
