Terminal and Printer Profiles
What is a Profile
• 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, haveto be forced when binary mode is selected. (Supported on
DTC 16iX/DTC 16MX 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.
