AI Thread Summary
The discussion revolves around a Visual Basic program utilizing MSComm for testing communication ports, specifically addressing the challenge of testing virtual ports (com3 and com4) associated with a game machine. The original poster successfully tests standard ports (com1 and com2) but seeks guidance on how to approach testing the virtual ports. Participants express uncertainty about virtual COM ports and suggest exploring options like a loopback test or checking for settings that might enable a virtual loopback feature. The conversation highlights the need for solutions or workarounds for testing virtual communication ports in a programming context.

Hi,

I am writing a visual basic program and used MSComm for testing communication ports of PC. It is working well.

At company, we have a game machine using two standard ports (com1 and com2 which can use MSComm to test) and virtual ports (com3 and com4). Of course, the program cannot test the virtual ports com3 and com4.

Anyone knows what should I do for my program or what I should consider of? Thanks a lot!

I have no idea what you are asking for.
 
Ooh NO!

Ooh!tell me O!.
 
I am as well suprised
 
I've never messed with virtual com ports before but I have a fair amount of experience with MSComm is VB. Is there some sort of loopback test you can do? Is there a setting for this virtual port that could do a 'virtual loopback'?

Thread 'Urgent: Physically repair - or bypass - power button on Asus laptop'

Asus Vivobook S14 flip. The power button is wrecked. Unable to turn it on AT ALL. We can get into how and why it got wrecked later, but suffice to say a kitchen knife was involved: These buttons do want to NOT come off, not like other lappies, where they can snap in and out. And they sure don't go back on. So, in the absence of a longer-term solution that might involve a replacement, is there any way I can activate the power button, like with a paperclip or wire or something? It looks...
