7-7
File-System Procedures
message control word to the application’s line buffer to indicate which terminal
responded. A call to READ while the line is in the READ state (a continuation
READ) causes Envoy to acknowledge the preceding message with the proper ACK
sequence, accept the EOT indication from the terminal, and resume polling of the
network.
SETMODE
Alters the line characteristics shown in Table 7-4.
Table 7-4. SETMODE Operations for ADM-2
