Default How to check tty/ttl connected to

I'm using minicom to connect to a variety of embedded devices. Usually I'm connecting from my linux workstation to OpenBSD devices. Now I am trying it the other way around. I do not get it working, since I'm not familiar with the way OpenBSD associates tty/ttl devices. Anyone knows how to check this?

dmesg:

Code:
uslcom0 at uhub0 port 4 configuration 1 interface 0 "Silicon Labs CP2104 USB to UART Bridge Controller" rev 2.00/1.00 addr 3
ucom0 at uslcom0 portno 0
Cheers

Are you trying to connect to a serial port ? I never tried this, but I think this may help OpenBSD FAQ 7

Also OpenBSD's manuals are great, maybe try:

Code:
man 4 tty
man 1 stty
man 1 tty

Indeed, the manpage told me that USB attached serial connections are associated with the letter U.

Code:
/dev/ttyU0
was the answer.
