RS232 (MSCOMM32) on windows 10 64bit

[tomk3]

Hello to all,


we read data from an external device and write it to a file with a little program (VERY old) in VFP using MSCOMM32

The PCs were XP then windows7 then windows10 32 bit (IT succeeded in transfering MSCOMM32 without changes in our tool)

Now they have a new PC with windows10 64 bit and an RS232 card and "transfered" MSCOMM again.

Problem
The program starts without error, but it receives "rubbish"
Interface settings are the same (9600 8 N 1 ) for program (active X) and interface card.

Questions
Does anybody know about that, why its receiving rubbish ?

Can you recommend another control (64bit) which can receive data and can be used with VFP / VFPA
(I found

https://www.adontec.com/,

but not sure on that)
or
Do you know a program which monitors RS232 and stores input into a file (background, without user interaction)


Thanks a lot in advance

regards
tom

If just as last resort solution, C# can easily read COM ports and could handle writing them to a file or provide them by other means, for example programmed as a service to which you could communicate via pipe or shared memory.

This would be a simple example which you could modify to write to a file instead of console output:

Instead of Console.ReadKey() just go to sleep indeterminate and you have a file replacing the data receival.

Hello Chriss,

good idea, thanks.
I will study it, exspecially how to handle the "stay in background and save if there is data".
The active-X has easy to use events for that. Its >15 years ago since I wrote that ....

Best regards

Hello,

just for the archive :

I found Scomm32 OCX on

https://comm32.axcol.com/

It has the same name for properties / events / methods like MSCOMM322
And it's free now.

Best regards
