CONTROL Request and Response
The CONTROL request can be used for any of the following
functions:
• To CONNECT the line by raising DTR and optionally
waiting for DSR.
• To DISCONNECT the line by dropping DTR and optionally
waiting for DSR to drop.
• To send a TTD sequence, indicating unreadiness to
send data.
• To send a WACK sequence, indicating unreadiness to
receive data.
• To send an EOT sequence, either to decline the chance
to bid for the line, or to reset the line after an
error.
The request buffers for these functions differ only in the
modifier field, as demonstrated below.
