I can use screen /dev/remserial1 and that works fine. I think I need to specify the baud rate and comm settings of the virtual device.
Sounds like setting the baud rate is what these serial programs are failing on... it's not acting like a serial port, it's acting like a virtual terminal. A terminal emulator that insists on a real serial port might never accept it.

hi. Im trying to install a switch.
And the manual says i should type a command including a SerialPortDevicePath. which is the filepath to serial port used for connection.
However.. nothing about how to find this info.
Could anyone help me where to find this path?
thx

LEARN ABOUT NETBSD
scc
SCC(4) BSD Kernel Interfaces Manual SCC(4)NAME
scc -- Zilog 8530 Serial Communications Controller interface
SYNOPSIS
scc* at ioasic? offset ?
DESCRIPTION
The scc driver provides support for the Zilog 8530 Serial Communications Controller (SCC) via the IOASIC found on DECstation 5000 models in
the /100, /20, and /240 series (supported by NetBSD/pmax).
Each SCC device has two serial ports. The DECstation 5000 model 20 provides one SCC device. Other models provide two, but one port of each
device is dedicated to mouse and keyboard input, respectively.
Input and output for each line may set to one of following baud rates: 50, 75, 110, 134.5, 150, 300, 600, 1200, 1800, 2400, 4800, 9600,
19200, 38400, or 57600.
Speeds up to 230400 are supported by the chip and the motherboard, but speeds higher than 57600 do not work reliably without an external
clock signal.
FILES
/dev/ttya
/dev/ttyb
/dev/ttyc
/dev/ttyd
The mapping from units to serial-hardware outlets is idiosyncratic. The even ports are wired serial connectors and the odd-numbered ports
are reserved for mouse and keyboard.
On machines with one port like Personal DECstations, the single device is ttya.
On the 5000/1xx and 5000/2xx, the first serial port (default serial console) is ttyc and the second port is ttya.
SEE ALSO intro(4), ioasic(4), ttys(5), MAKEDEV(8)HISTORY
The scc driver first appeared in 4.4BSD.
The scc driver was also used for the IOASIC SCC found in DEC Alpha model 3000 TurboCHANNEL based systems; NetBSD/alpha has since been con-
verted to use the machine-independent zstty(4).
BUGS
The IOASIC provides internal DMA channels that can be programmed to transfer up to 4096 bytes of data into, or out, of an SCC without further
software intervention. This feature of the IOASIC is not yet supported.
The mapping from device-special files (major and minor number) to chip and port is arguably backwards. ULTRIX tries to hide the hardware
mapping, but NetBSD does not. Users wanting to use ULTRIX compatible tty names /dev/tty0 and /dev/tty1 for the scc comm-port lines should
make links or device-special files which match their hardware setup.
