Printer modem ports
•
None—use for a directly-connected printer.
•
Standard DCE—use for a modem-connected printer, where a link is made
at the device.
•
DCE high—use for a terminal connected via a modem/multiplexer.
•
DTE—use when the connection to the terminal is initiated by the host.
Specifies the data transfer mode to be used when opening the connection on the port.
Possible values are :
ASCII
BINARY
If BINARY is used, the DTC does not detect special characters received from the
device; all received characters from the device are sent to the system without
interpretation.This is also known as transparent mode.
The setting ASCII is used by default.
Enter the ASCII character you want to use as the escape character that signals when
to escape from the data transfer process. Non-displayable ASCII characters are
specified in caret-character (^character) format. The literal caret (^) and backslash
(\) are escaped with a backslash. This field must be filled. The default escape (from
data transfer) character is ^K (Ctrl-K).
The escape from data transfer character is used at a terminal to switch from the host
system to the DTC terminal user interface. This value applies only to terminal ports
for which switching is enabled (see "Enable Switching" on page 102).
If switching is enabled when the DTC is configured, you can logon to a terminal.
Press any key on the terminal to get a DTC prompt. You can then logon to your
system. Later, if you wish to leave your system but not log off, you enter the escape
from data transfer character (Ctrl-K). You see the DTC prompt again and can enter
a DTC user terminal interface command. You can even connect to another system.
The number of systems you can connect to is determined by the Maximum
Number of Sessions.
Specify a value between 1 and 5. The maximum number of sessions is the greatest
number of system connections allowed on a terminal at any one time. This value
applies only to terminal ports for which switching is enabled.
