The cable and adapters is what I was trying to
get away from.
The best that I can read the vms faq.5 is that
something like this needs to be done:
MMJ DB9-DEC
---------------- ----------------
1. DTR Frame gnd
2. Transmit HI Transmit data
3. Transmit LOW Receive data
4. Receive LOW RTS
5. Receive HI DTR
6. DSR DSR
7. Signal gnd
8. Console present
9. Console present
---------------- ----------------
a) jumper dtr/dsr jumper dtr/dsr/rts
b) jumper 3/4 gnd and tie to signal gnd
c) jumper dtr/dsr
d) jumper console pins
e) Tie TX/RX LOW to signal gnd
f) Tie TX HI to receive ata
g) Tie RX HI to transmit data
The net effect should be a classic 3 wire serial
cable.
What I want to do is confirm that before I do
anything strange to the console port on the cpu
card or the VTxxx terminals.
Thanks
