LOG DSK0:[1,4]
VTSER/S MAGICWORD
The password, which appears in bold type in the example, can be up to 10 characters long; VTSER does
not distinguish between upper and lower case letters. To protect your VTSER password, the file
containing the password should be located on a logical disk device which can’t be accessed over the
network. The system initialization command file with the above VTSER job should also contain the
command SET NOACCESS DSK0:. If you do not prevent access to DSK0: anyone could read your
VTSER password over the network and then make a virtual terminal connection to your computer. You
may also choose to locate your VTSER.JIN file on some logical disk device other than DSK0:. For
example:
SETJOB VTSER,VTSER,32K,DSK11:VTSER.JIN[200,1]
For best protection from unauthorized virtual terminal connections, make sure you use
SET
NOACCESS to prevent access to the logical device that contains the VTSER.JIN file.
If you are using AMOS 2.2 (or later) software releases with extended disk format, you can create
or modify files with user privileges that prevent them from being read over the network. See your
AMOS documentation for information on creating files with user privileges.
TDVDEF (AMOS 2.1 and Later Only)
The TDVDEF statement (valid only with AMOS 2.1 or later releases) must be inserted into your system
initialization command file after the last TRMDEF statement and before the first NETINI command to
load the specified terminal drivers for use by virtual terminal connections. Without the TDVDEF
statement, the only terminals supported as virtual terminal connections would be those defined in the
normal TRMDEF statements on the local node.
Using the TDVDEF statement, you can load any or all of your terminal driver files into memory when
your computer boots. You can follow the TDVDEF statement with the wild card symbol (*) and all the
TDV files in the local node’s DSK0:[1,6] will be loaded into memory, or you can follow the TDVDEF
statement with specific TDV names:
TDVDEF *
or:
TDVDEF AM65.TDV, AM72.TDV, AM62A.TDV
Allocating Message Buffers with MSGINI
AMOS’s Inter Task Communication System, the foundation for all of AlphaNET, requires buffer space
within the system communication area. This space is allocated by the MSGINI command. This command
must be performed before the first SYSTEM command, and takes as an argument the amount of memory
to allocated. A minimum of 16K should be allocated when using AlphaNET.
