I'm using NetBSD-1.6 on a Sparcserver-10 with serial console.
Now I tried to connect a device to the second serial.
I've build a splitter cable and used /dev/dtyb, but the device is
neither receiving nor sending any data.
Acording to an LED tester the right lines have signal, and DTR goes
active once I start tip on the device.
But no activity on TxD when I type something.
The console still works fine.

My /etc/remote reads:
dtyb|:dv=/dev/dtyb:br#9600:pa=none:dc:
