To change Com port settings or any port setting it is done in the device manager section of windows. This is not to say making changes in the ports will cause an adapter to usb to work.
The true issue for us anyway is the race software and windows does not know how to understand a printer port or com port signal via adapter to USB when related to the race software being used. Any software designer who says his software works with adapters needs to support that claim...not the Hardware designer.
So we offer a work around that seems very worth while: Windows Remote Desktop Manager. We are not experts at this option, no more than we are experts at the race software..we are hardware experts...and that is where we hang our hat.
Perhaps with enough user presure the software designers can figure out and resolve the communication issues for all adaptor types....but that is not something we can do nor can the end user even if you are a computer tech etc....My training goes back to DOS before Windows I have deep solid state background and have worked for major corprate and government icons...I know hardware and how it works.
For the USB WORK AROUND use a dedicated race pc, any networkable box, you can find with the proper op sysem for the race software and for the WRDM option. With a pc that has a printer port or the port type you want installed on the lap timer....then use Windows Remote Desktop Manager to open the race software to run and manage races, from your laptop, smart phone or other networkable hardware that works with WRDM. Which is great for club races, users could log on to the race pc and download or print out their race results or club standings etc.
No WRDM it is not a Plug and Play option by our standards but it is a very techy one
that gives you many more upscale options than an adapter to USB. Just like anything it has a learning curve, once past that, you are far ahead of the others
For what it is worth the developer of Lap Timer 2000 says his software works with adaptors purchased from radio shack and he provides the part numbers...He should also provide the support for his claims and softrware. The developer of Race Coordinator asked some well informed tech folks about the issue and some say they have had luck with a rockfire adapter to usb...but as mentioned NO ONE is saying these work for most &/or all end users...WE SURE ARE NOT BUT WISH WE COULD
"Some luck" in our opinion is laps were triggered but not reliably or correctly enough for us to offer support or a hardware / software solution for adaptor to USB configuration changes.Our resolution to the usb issue so far is on the network side or windows side, not Radio Shack or Rockfire.
