Ports
If your keyboard doesn't have a Break key, an equivalent can be specified with the Set/Define Ports Local
Switch command, or with the Set/Define Ports Break Character command.
Local>> DEFINE PORT 2 LOCAL SWITCH '
Local>> DEFINE PORT 2 BREAK CHARACTER '
There are several examples of how the Port Break command and the alternate Break character work
together. The effect of the Break character depends on the type of connection and how Break processing is
configured. The examples assume that an alternate Break character has been defined for the user's port.
An SCS serial port user Telnets to a network host and types the alternate Break character.
Local Break: The user is returned to the SCS Local> prompt.
Remote Break: A Telnet Break IAC sequence will be sent to the host.
An SCS serial port user makes an SSH connection to a network host and types the alternate Break
character.
Local Break: The user is returned to the SCS Local> prompt.
Remote Break: Nothing happens, because there is no way to generate a Break across an SSH
connection.
An SCS user on serial port 2 issues a command to port 3 and types the alternate Break character.
Local Break: The user is returned to the SCS Local> prompt.
Remote Break: A Break condition will be generated on port 3.
A user Telnets into the SCS, has a default alternate Break character from template port 0, and types
the alternate Break character at the Local> prompt.
Local or Remote Break: Nothing happens, because the user is already at the Local> prompt.
A user forms a TCP connection from a network host to port 7 on the SCS (for which an alternate Break
character has been defined) using socket 2007, then types the alternate Break character.
The 20xx range of sockets performs Telnet IAC interpretation.
Note:
Local Break: If the alternate Break character is detected in the datastream, nothing happens. If a Break
condition is detected on the serial port, nothing happens.
Remote Break: If the alternate Break character is detected in the datastream, a serial Break condition
is generated on the port. If a Break condition is detected on the serial port, a Telnet Break IAC
condition will be sent on the network connection.
A user forms a TCP connection from a network host to port 7 on the SCS (for which an alternate Break
character has been defined) using socket 3007, then types the alternate Break character.
