Reliable serial port emulator recommendations?

[Walterhill]

Hi! Can anyone recommend a reliable serial port emulator? I need one for my project.

I’d really appreciate it if you could share your experience and let me know which options worked well for you.

Thanks!

Are you looking for a way to connect an older device to USB to the computer?

Example, I got this cable that replaces a Meade Telescope #505 Cable which was originally a phone connector <-> serial port. https://www.amazon.com/dp/B0B3TTGKCK?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1

I’ve had a good experience with https://www.virtual-serial-port.org/ I’ve used it on Windows for a few projects and it’s been reliable and easy to set up. It lets you create virtual COM port pairs and more complex configurations without much effort, and I haven’t had any stability issues.
