7: Example BSCTRAN Usage
DC 900-1406E 109
7.3 Command Procedure Example
The VMS DCL command procedure shown in Figure 7–3 demonstrates most of the
commands and options of the BSCTRAN program. The command procedure uses DLI
sessions
FWY0B0L2 and FWY0B0L3. The connection is bsc0, and the Freeway server name
is
freeway0. The demonstration requires Freeway server freeway0, ICP 0, links 2 and 3
to be connected with a loopback cable. As a rule, Freeway servers are configured at
Simpact for external clocks, because in a production environment the clocking is pro-
vided by modems (that is, the clocking is external).
Note
A UNIX command file would omit the beginning and final lines
(those lines starting with a “$”).
This procedure assumes that the BSC 3780 software is already downloaded to the ICP.
In an actual situation using two remote sites, this command procedure would be split
into two parts, one to control each site.
Caution
All files sent in a loopback test, such as the Figure 7–3 example,
must be small enough to be entirely contained within ICP mem-
ory, or the ICP will hang during the send operation. The files used
in the SEND commands of Figure 7–3 are not provided with the
BSCTRAN product. If you wish to use a similar procedure to test
BSCTRAN, you can use any moderately sized text, object, and exe-
cutable files for the SEND commands.
Note
The procedure in Figure 7–3 starts link 2, then link 3. A diagnostic
message will be reported indicating that link 2 has not started. You
can ignore this message because when link 3 starts, link 2 will
detect link 3’s carrier signal through the loopback cable. This will
cause link 2 to start itself.
