98 CHAPTER 7: POS TERMINAL ACCESS SERVICE
If the FCM interface is used as POS access interface undo modem cannot be
configured. If another interface is used as the POS access interface undo modem
must be configured.
Since POS access does not support flow control, the interface should be
configured with the flow-control none command.
If the POS access port is connected to the POS terminal in asynchronous mode,
and the POS asynchronous port does not send a DSR-DTR signal, it is necessary to
configure the command undo detect dsr-dtr on the interface. If the POS access
port is connected to the FCM interface via dial-up, it is unnecessary to configure
the undo detect dsr-dtr command.
3 Configure POS Application
The POS access router connects to the UNIX FEP in the following two ways:
asynchronous connection and TCP/IP connection. The commands used for
configuring the POS application are different in the two modes. Connecting to the
UNIX FEP through the Ethernet is called a TCP/IP connection, while connecting
through the asynchronous serial port is called asynchronous connection. No
matter how the connected is made, it is necessary to configure the POS
application to UNIX FEP for the terminal.
Please perform the following configuration in system view.
Table 74 Configure a POS application
By default, no POS application is configured by the system.
4 Configure POS Application Interface
POS application interface should operate in posapp mode.
Please perform the following configuration in asynchronous interface view.
Table 75 Configure the asynchronous connection interface to operate in POS application
mode
When the POS access router is connected to the UNIX FEP in asynchronous mode,
the interface should operate in posapp mode.
This command can be configured only when the active interface is configured with
the command async mode protocol
Only after the command undo modem is configured, can data be transceived
normally.
