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.
