Another possible problem is that the remote end response contains
normal words mixed in with strange characters, many of which are left
brackets ([). This usually indicates that the remote device is sending
ANSI display control sequences, and your terminal does not recognize
them (ANSI stands for American National Standards Institute).
On a PC, this can generally be remedied by first disconnecting the call,
editing the PC’s CONFIG.SYS file to include the line
DEVICE=ANSI.SYS
rebooting the PC, and then trying the call again. (For a log off
procedure, see the alternative method under “Disconnecting a Data
Call,” below.)
Note:
If the terminal device is not a PC, or the suggested remedy
does not seem to solve the problem, and then you will need
to consult the documentation for your dedicated terminal, or
for your PC and any software involved.
Disconnecting a Data Call Most remote systems will have a command or menu selection for
logging off. When you select the appropriate means, the remote system
will usually disconnect or hang up. The PBX will disconnect from the
call and, after a moment, the data module will send the following
message to your display:
NO CARRIER
Alternatively, you can use the following log off procedure:
Selection: +++
OK
The prompt Selection: is simply a representation of how the remote
system might ask you for your next command or menu selection. Type
the escape sequence (default is
+++)
but do
not
press
[ Enter ].
When the data module responds with OK, type the command line:
ath
[ Enter ]
The PBX will disconnect from the remote end device, and the 7400B
will send the OK message to the terminal display.
