This RFC specifies a standard for the ARPA Internet community. Hosts on

the ARPA Internet are expected to adopt and implement this standard.

1. Command Name and Code

TRANSMIT-BINARY 0

2. Command Meanings

IAC WILL TRANSMIT-BINARY

The sender of this command REQUESTS permission to begin

transmitting, or confirms that it will now begin transmitting

characters which are to be interpreted as 8 bits of binary data by

the receiver of the data.

IAC WON'T TRANSMIT-BINARY

If the connection is already being operated in binary transmission

mode, the sender of this command DEMANDS to begin transmitting

data characters which are to be interpreted as standard NVT ASCII

characters by the receiver of the data. If the connection is not

already being operated in binary transmission mode, the sender of

this command REFUSES to begin transmitting characters which are to

be interpreted as binary characters by the receiver of the data

(i.e., the sender of the data demands to continue transmitting

characters in its present mode).

A connection is being operated in binary transmission mode only

when one party has requested it and the other has acknowledged it.

IAC DO TRANSMIT-BINARY

The sender of this command REQUESTS that the sender of the data

start transmitting, or confirms that the sender of data is

expected to transmit, characters which are to be interpreted as 8

bits of binary data (i.e., by the party sending this command).

IAC DON'T TRANSMIT-BINARY

If the connection is already being operated in binary transmission

mode, the sender of this command DEMANDS that the sender of the

data start transmitting characters which are to be interpreted as
