# To activate use of DNC 1.4 use this line:
# cp /dev/null /etc/DNC1.4
# ln /dev/tty4 /dev/dnctty (Current loop)
ln /dev/tty9 /dev/dnctty (RS-232)
ln /dev/tty5 /dev/rdrtty
ln /devtty6 /dev/1pr
ln /dev/tty7 /dev/bcrtty
NOTES:
Excellon suggests using a short haul
modem at the file server. The modem output is connected to the third
lug bar from the top of the Octal Serial Card (OSI Card). This is a
current loop connection defined as tty4.
Normally
we use a direct, serial, RS-232 connection to one of the DB-9 connectors on
the CCI-1 board (typically J7).
