System Management Release Notes
4.41 Terminal Fallback Facility
To start TFF, invoke the TFF startup command procedure located in
SYS$MANAGER, as follows:
$ @SYS$MANAGER:TFF$SYSTARTUP.COM
To enable fallback or to change fallback characteristics, invoke the Terminal
Fallback Utility (TFU), as follows:
$ RUN SYS$SYSTEM:TFU
TFU>
To enable default fallback to the terminal, enter the following DCL command:
$ SET TERMINAL/FALLBACK
OpenVMS Alpha TFF differs from OpenVMS VAX TFF in the following ways:
• On Alpha systems, the TFF fallback driver is named SYS$FBDRIVER.EXE.
On VAX systems, the TFF fallback driver is named FBDRIVER.EXE.
• On Alpha systems, TFF is capable of handling 16-bit character fallback. The
OpenVMS Alpha fallback table library (TFF$MASTER.DAT) contains four
more 16-bit character tables than the VAX library. Table 4–4 describes these
additional tables.
Table 4–4 TFF Character Fallback Tables
Table Name Base Description
BIG5_HANYU BIG5 BIG5 for CNS 11643 (SICGCC) terminal/printer
HANYU_BIG5 CNS CNS 11643 (SICGCC) for BIG5 terminal/printer
HANYU_TELEX CNS CNS 11643 for MITAC TELEX-CODE terminal
HANGUL_DS KS KS for DOOSAN 200 terminal
These tables are used mainly by the Asian region. Also, the table format was
changed due to the support of 16-bit character fallback.
• On Alpha systems, the TFU command SHOW STATISTICS does not display
the size of the fallback driver (SYS$FBDRIVER.EXE).
RT terminals are not supported by TFF.
For more information about the Terminal Fallback Facility, refer to the now
archived OpenVMS Terminal Fallback Utility Manual on the OpenVMS
documentation website:

4.42 User Environment Test Package (Integrity servers Only)
V8.2
The User Environment Test Package (UETP) can be used with the following
cautions:
• During the load phase, there are sporadic access violations in UETMEMY01.
This does not terminate execution or really affect the validity of the run.
UETP is still useable and produces valid results.
