Adding COM ports with COM0COM

#1

Unread post by Douglass Allen »

I have spent many hours trying to add COM ports to a several windows 10 computers with COM0COM. When I try to start up the 64 bit COM0COM version, I get the following message-

"This package does not include 64 bit driver required for your system." I find nothing about a 64 bit driver when I do a Google search.

Using the 32 bit COM0COM software I get a message-

"SDR needs a COM port to control it and none were found...."

Program Options Port Selections shows no ports.

Not sure if I'm using the 32 bit or 64 bit Console. Does it matter?

Is it possible for an 80 year old to figure all this out even with some much needed hand holding?

Hi Doug

Firstly, if you have a 64 bit copy of Windows 10 (probably 95% of all installations of Win10 are 64 bit I would think) then always download and use latest 64 bit download of SDRC, which currently is 3.0.27:

https://www.sdr-radio.com/download

The link at top of page that says "Select 32 bit or 64 bit" does not take you to the SDRC download, it takes you to a link on advice on how to see if you have 32 bit or 64 bit Windows. Maybe do that first to find the version of Windows that you have, then come back to the link above and carefully scroll down to the big green "Download" graphic with "3.0.27" on it, then select relevant download version, 32 bit or 64 bit (almost certainly you will want the latter).

Loads of instructions on use of SDRC here:
https://www.sdr-radio.com/

Go to top of screen and hover over the menus at the top of screen. There is much more info here than it seems at first sight by using the drop-down menus by hovering over the buttons at top of screen.

Re Com0Com. Never used it but I have had great success with VSP Manager from K5FR. Just email him with your call sign and he will email a link to download it. I find it very easy to use.

See these two pages for more info:

Good luck.

When you define a com port pair such as COM3 x COM4 make sure the "Use Ports class" check box is checked for both ports.

Thank you Max and jddow. I just this morning downloaded the latest 64 bit 3.1 version. I spent many, many hours last summer with an earlier SDR Console before giving up. Now I'm trying again
Yes, I have read Loads of instructions on use of SDRC here:
https://www.sdr-radio.com/ many times including the part on Serial Ports.
Yes, I have "use Ports class" for both ports and still the ports are listed in Device Manager on their own line and not under Ports.
I have watched this video- Creating virtual COM ports with com0com and it shows the virtual ports under te Device Manager Ports and not on their own com0com line so I think that's the problem. It could be something else.
jdow, how did you copy and paste the com0com screen? I tried the snaipping tool and it doesn't paste to these forum posts.
