IGNORANCE IS BLISS. I decided to force the serial port open/closed another time. Set up a new OMS profile but still got the same message. "Serial Port in use by another application."
So, I did what any self-respecting Macophile would do...I decided to ignore it. Went to SoundBridge loaded up my file, and whaddaya know. It's working.
I don't know why the error message comes up, maybe port is in use by another application other than the modem? Maybe port is in use by OMS (thank you Captain-Mac-Obvious)?
I don't know why...and frankly, I don't care...my Mac is doing what I knew it could...delivering the goods.
Thank you to beachycove, Graham Hinton, QuadSix50, Paralel and Kallikak.
In the godsend category, thanks to ppuskari. Your empathy and assistance were nothing short of miraculous.
A Mac-tacular thanks goes out to your friend and mine...Bunsen!
He stuck with me through it all. Never giving up. Never without creative input. My guardian angel of tech-support. If it wasn't for Bunsen, I would have put my Mac back in storage and given up.
Bunsen, I don't see myself coming down under anytime soon, but I vow to buy a Fosters for our local Aussie in your honor.
I know I'm not at the Academy Awards™...but I've seen too many forums where things just trail off. No acknowledgement. No thanks.
So to all who maintain and contribute to this forum....
Thanks.
Sincerely,
Jason K
