Data transfer Specifies the mode of data transfer. For back-to-back connections, the
field can be either ASCII or binary. If the profile will not be configured
for back-to-back connections, enter 1 for ASCII. The default is ASCII.
Escape from data transfer character Optional field which specifies the character
which will return the terminal user to the DTC user interface. Field
applies only if switching is enabled. Field may be either an ASCII
character or a control character entered as ˆchar where char is any
letter, [, \, ˆ, _, or ]. If field is left blank, you will not return to the
DTC user interface before logging off the session.
Maximum number of sessions The number of concurrent sessions allowed from a
terminal. The maximum number of sessions allowed is 5 and the
default is 1. If the connection is established to a HP e3000 that is
configured as host-based then only one connection to that host is
allowed. If the connection is established to a PC-based system and the
DTC port configured as non-nailed, then you may establish up to the
maximum number of sessions specified. Only one connection is active
at any given time. All other sessions are in a suspended state. See
Appendix C, “DTC User Interface,” for a description of the DTC user
interface commands.
Enable port? Specifies whether communication can be established to the port. Enter
an N to disable the port. The default is Y. If disabled, no connections
can be established to the port.
DTC user interface timeout? Specifies whether the DTC user interface timeout is
active. If enabled, terminal connection to the DTC user interface is
automatically disconnected after the timeout period defined on DTC
User Interface screen (Figure 8-3). Field is valid only if switching is
enabled in the “Enable switching?” field. Enter a Y to enable the
DTC user interface timeout, the default is N.
Enable switching? Specifies the switching capability of the port. Enter a Y to enable
switching. The default is N. If switching is enabled, you are allowed to
access more than one system. You will see a DTC prompt that is
specified on the DTC User Interface screen Figure 8-3 in Chapter 8,
“Additional DTC Configuration.” Connection to other systems on the
LAN can be made by entering connect system name at the DTC
prompt (refer to Chapter 8, “ Additional DTC Configuration,” for more
information on the DTC user interface). If switching is disabled, the
terminal will be automatically connected to the host defined in the
“Default destination” field.
Enable keep alive? Specifies whether “keep alive” mechanism is to be activated.
When there is no data transfer between the and the DTC and the
system, then the “keep alive” mechanism is used to detect if the
connection is still there. The default value is Y (enable). Enter an N to
disable the field. Not applicable for DTC 48 without the memory
extension. This feature is only applicable for ARPA (TCP/IP)
connections.
Automatic connection? Specifies whether a connection is automatically established to
the system specified in the “Default destination” field. Enter a Y to
enable automatic connection. The default is N. If enabled, the DTC
senses the modem signal’s rise and automatically connects the device
to the value of “Default destination”. “Allow :HELLO logon?”
