TELNET SUPPRESS GO AHEAD OPTION
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
2. Command Meanings
IAC WILL SUPPRESS-GO-AHEAD
The sender of this command requests permission to begin suppressing transmission of the TELNET GO AHEAD (GA) character when transmitting data characters, or the sender of this command confirms it will now begin suppressing transmission of GAs with transmitted data characters.
IAC WON’T SUPPRESS-GO-AHEAD
The sender of this command demands to begin transmitting, or to continue transmitting, the GA character when transmitting data characters.
IAC DO SUPPRESS-GO-AHEAD
The sender of this commannd requests that the sender of data start suppressing GA when transmitting data, or the sender of this command confirms that the sender of data is expected to suppress transmission of GAs.
IAC DON’T SUPPRESSS-GO-AHEAD
The sender of this command demands that the receiver of the command start or continue transmitting GAs when transmitting data.
Go aheads are transmitted.

4. Motivation for the Option
While the NVT nominally follows a half duplex protocol complete with a GO AHEAD signal, there is no reason why a full duplex connection between a full duplex terminal and a host optimized to handle full duplex terminals should be burdened with the GO AHEAD signal. Therefore, it is desirable to have a TELNET option with which parties involved can agree that one or the other or both should suppress transmission of GO AHEADS.
5. Description of the Option
When the SUPPRESS-GO-AHEAD option is in effect on the connection between a s...
