I know the dec3000/600 won't boot linux. I'm planning to install netbsd on
I tried toggling the S3 switch, but in either position there doesn't seem
to appear anything at my console.
when I start 'statserial' on /dev/ttyS1 to see activity on the serial
port,I get this result:
Signal Pin Pin Direction Status Full
Name (25) (9) (computer) Name
----- --- --- --------- ------ -----
FG 1 - - - Frame Ground
TxD 2 3 out - Transmit Data
RxD 3 2 in - Receive Data
RTS 4 7 out 1 Request To Send
CTS 5 8 in 0 Clear To Send
DSR 6 6 in 1 Data Set Ready
GND 7 5 - - Signal Ground
DCD 8 1 in 0 Data Carrier Detect
DTR 20 4 out 1 Data Terminal Ready
RI 22 9 in 0 Ring Indicator
When rebooting the DEC3000/600, only the DSR is going from 0 to 1 to 0 and
back to 1 again.
but I'm a bit puzzled about the TX and RX fields not holding either a 0 or
maybe you could shed some light on this ?
