• The type of modem used, if any.
• Specify the protocol used to establish a modem link between the DTC and the
attached device.
• The type of parity that will be used if parity is enabled.
• The mode of data transfer in back-to-back connections, can be ASCII or binary.
• Specify whether ENQ/ACK flow control is enabled.
• Number of stop bits to be used for asynchronous characters. (Supported on
DTC 16iX/DTC 16MX and DTC 72MX only.)
• Whether to enable flow control between the DTC port and the connected device.
• Specify whether “keep alive” mechanism is to be activated to detect if connection is
still there. (Does not apply to the DTC 48 without the memory extension.)
• Specify whether port configuration parameters; data length and parity, have to be
forced when binary mode is selected. (Supported on DT C16iX/DT C16MX and
DTC 72MX only.)
• Specify whether the DTC will establish a connection automatically when the modem
lines are raised.
• Specify whether hardware handshaking will be used.
• Specify destination node if automatic connection is enabled.
• A string that may be sent to the device under specific conditions such as after a port
reset, or a connection is closed.
See the “Host Profile Screen (Host-Based)” section, for more information on how to
configure extended switching ports.
Terminal Types
A terminal type is a collection of characteristics that cause a terminal to act and react in
a specific way. It defines the relationship between the terminal and the MPE/iX
operating system. Three terminal types are supplied with MPE/iX: terminal type 10,
terminal type 18, and terminal type 24.
Terminal Type 10
Use terminal type 10 for Hewlett-Packard terminals and Hewlett-Packard personal
computers running in terminal emulation mode. This type enables the XON/XOFF
protocol (both receive and transmit). It supports block mode data transfers and can
detect data transmission errors through the use of parity checking. This terminal type
can work with some non-Hewlett-Packard devices, but none of them are supported.
NOTE The system console uses terminal type 10, but it does not have the same functionality as
other terminals connected and configured as terminal type 10. A UPS also uses terminal
type 10, but it has different functionality from other devices connected and configured as
terminal type 10.
Terminal Type 18
Use terminal type 18 for non-Hewlett-Packard devices. It differs from terminal type 10
in the following ways:
