 NT7D16 Data Access card

Two dialing parameters, DCD control, and Answer mode, can be modified by 
both keyboard and Hayes dialing commands.

The Hayes dialing mode also allows the user to modify the Input echo control, 
and Prompt/Result codes transmit control. With keyboard dialing, the Input 
echo control and Prompt/Response codes control are determined by the 
downloaded parameters. They cannot be altered through dialing commands.

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 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.

The record can be edited by using the backspace and escape characters.

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.
