NT7D16 Data Access card
The DAC maintains separate buffers for keyboard and Hayes dialing modes.
Changes made to a given parameter in one mode do not affect that
parameter in the other mode. When a dialing mode is selected, the DAC
copies the corresponding dialing parameters into the active buffer. This
buffer controls the call processing.

If the DAC receives an incoming call while idle, the most recent dialing mode
is used to answer the call.

User input
User input may include either upper or lower case ASCII characters.
All entries are accumulated in an input record. This record is completed with
a Terminator character. For keyboard dialing, this character is always <CR>;
for Hayes dialing, it can be user defined (but default to <CR>). The entries
are not processed until the Terminator character is received.

The input record is limited to 43 characters, including the Terminator, but
excluding any ignored space characters.
excluding any ignored space characters.
The record can be edited by using the backspace and escape characters.
Operating modes
There are sixteen possible RS-232-C operating modes with three basic
common modes of operation which correspond to three types of equipment
connected to the DAC. The three modes are: modem, terminal, and host.
Host mode is a subset of the terminal mode, which only suppresses the
prompts at the terminal.

Host mode is a subset of the terminal mode, which only suppresses the
prompts at the terminal.
The fourth mode, gateway, is a subset of the modem mode and is not
normally used. This mode is useful if the attached modems do not have
Ring Indicator lead. The application used is inbound modem pooling.
normally used. This mode is useful if the attached modems do not have
Ring Indicator lead. The application used is inbound modem pooling.
The different modes enable the DAC to connect to different types of devices
such as modems (modes 0, 1, 2, and 3), gateways (modes 4, 5. 6, and 7),
hosts (modes 8. 9. 10, and 11), and terminals (modes 12. 13. 14, and 15).
After selecting the appropriate group (that is, modem, gateway, host, or
terminal), the installer should study the four different modes in that group
to make the proper selection. See
