BBB using host mode USB to serial adapter

Hi, I am trying to run a program called “Lady Heather” that controls GPSDOs and rubidium oscillators (in my case) on a Beaglebone Black (BBB) later model. I have it booting, lxde desktop is up and Lady Heather starts after much, and I mean much, screwing around. Now I need to talk to the rubidium oscillator using RS232. I’ve done this in the past using a USB to RS232 adapter on a PC. I plugged the same USB/RS232 adapter into the BBB through a hub that I use for my keyboard,mouse and tried several of the tty ports by starting the Lady Heather code with a -1 or -2 for the port number without luck. I assume I have to load a driver? Most of the posts I read are all trying to talk from a PC to the BBB using level shifting into the BBB serial port on the 6-pin connector, opposed to what I’m trying to do. Anyone have any pointers?

Thanks!

I found an entry that said to try /1u which signals to use the 1st USB tty port, and it worked! Ha, I started this project the day before Thanksgiving and can’t believe it is working. The AI systems available make things very easy. Thanks for reading.
