UUCP Implementation Description
9.10. Device Types
The currently supported device types are:
Type Code
ACU
ACUDNll
ACUDF02
ACUDF03
ACUVENTEL
DIR
DEC DNll
DEC DNll
Device
DEC DF02 (300 baud only)
DEC DF03 (1200 baud only)
Ventel MD212 Plus
Hardwired Line.
UUCP Installation
The DNll is only available on DEC PDP-II and VAX systems. The DEC DF02, DF03, and
Ventel MD212 Plus can
be
connected to any system using a standard RS232 terminal interface.
When connecting one or these devices to a terminal line, the device node (/ dev /ttyz) should be
renamed (to /dev/cuaO ror instance) to emphasize that the line is for dialout only and to
prevent accidentally starting a login process ror that line.
The device type specified in the L-device, file should be one of those listed above, optionally
qualified rurther by additional characters after the device type. The device type specified in the
L.,y, file should be a prefix of one of the devices specified in the L-device, file. For example,
assume you have two DF03's, one connected to a local telephone line and the other connected to
a WATS line. The L-dev;ce, file could be set up as follows:
ACUDF0310cal cuaO cuaO 1200
.ACUDF03wats cuaO' cuaD 1200
To call a system using only the WATS line, specify ACUDF03wats in the device type field.
Similarly, to call a system using the local telephone line, specify ACUDF031ocai. To call a
8y~
tem using either DF03, speciry ACUDF03 in the
L.,",
file.
Note that the telephone numbers specified in the L.'II' file will have a format dependent on the
ACU device type. This is a deficiency which may
be
corrected in the future.
10. Administration
This section indicates some events and files that must be administered for the uuep system.
Some administration can be accomplished by ,/a ell file, initiated by erontab entries. Others may
require manual intervention. Some sample ,/aeU file, are given toward the end of this section.
10.1.
SQFILE - ,Sequence Check File
SQFILE is set up in the program directory and contains an entry for each remote system with
which you agree to perform conversation sequence checks. The initial entry is just the system
name of the remote system. The first conversation adds the conversation count and the
date/time of the most resent conversation. These items are updated with each conversation. If
a sequence check fails, the entry will have to be adjusted manually. Note that this feature is
rarely used.
