Application Process Controlling a Remote Terminal
An application process controls the end-to-end interface between the remote terminal
and the Tandem system. The application uses standard Guardian file-system
procedure calls. The application does not have direct access to the packets, but it can
obtain and modify some packet fields through the procedure calls.
The application can use the procedure calls to perform the following functions:
open the terminal
obtain the remote DTE address
transmit and receive data
set the terminal to conversational mode or block mode
change the PAD parameters
disconnect the virtual circuit
set the parity
set the spacing control
set the packet size
set or fetch various information in the Reset, Clear, Restart, or Call Request
