X.3 ITI Parameters 14 Linefee Padding ------------------ Para- meter Description ----- ----------- 0 National Options Marker This parameter serves to mark the division between International (X.3) parameters and Network Dependent (e.g., Telenet) parameters in an X.28 or X.29 parameters list. All parameters preceding the marker are X.3, and those following are Network Dependent. Values may be: 0 CCIT specified value 33 Telenet permitted value Telenet accepts either value. Whenever possible, the CCITT specified value of zero should be used. 1 Escape to Command Level This parameter allows the terminal to initiate an escape from Data Transfer Mode, in order to send a command to the PAD. Values are: 0 Escape not possible 1 Escape possible (default) 2 Echo This parameter provides for all characters received from the terminal to be transmitted back to the terminal, as well as being interpreted and forwarded by the PAD to the the remote DTE. Values are: 0 No echo 1 Echo (default) 3 Data Forwarding This parameter allows the PAD to recognize defined character(s) received from the terminal as an indication to complete assembly of characters to forward a DATA packet to the remote DTE. Values may be OR-ed together (e.g., value of 3=1+2=Alphanumerics plus Carriage Return) 0 No signal 1 Alphanumerics 2 Carriage Return (Default) 4 Escape 8 Editing Characters 16 Terminators 32 Form Effectors 64 Control Characters 128 Other Characters (Not valid according to CCITT recommendations) 4 Idle Timer Should the interval between successive characters received from the terminal exceed the selected Idle Timer delay, the PAD will terminate assembly of characters and forward a DATA packet to the remote DTE. Values are: 0 Timer disabled n multiples of 50 ms (.05 seconds), where 1<=n<=255. n=1 n=1 and n=2 not recommended. (Default is 80, 4 seconds) 5 Ancillary Device Control This parameter enables flow control between the PAD and the terminal. The PAD uses the XON and XOFF characters (decimal 17 and 19) to indicate to the terminal whether or not it is ready to accept characters. Values are: 0 No use if XON/XOFF (default) 1 Use XON/XOFF 6 Suppression of Service Signals This parameter provides for the suppression of all messages sent by the PAD to the terminal. Values are: 0 Signals not transmitted (messages not sent) 1 Signals transmitted (messages sent) (Default) 7 Break Options This parameter specifies the action taken on receipt of a Break signal from the terminal. The only valid values are: 0 Do nothing (Default) 1 Send INTERRUPT Packet to Host 2 Send RESET Packet to Host 8 Escape to PAD Command State 21 Flush-on-Break (Discard Output, Send Indication of Break and Send INTERRUPT) 8 Discard Output This controls transmission of data to the terminal. Values are: 0 Normal data delivery to the terminal (Default) 1 Discard all output to the terminal 9 Carriage Return Padding This parameter provides for automatic insertion by the PAD of null character padding after the transmission of a carriage return to the terminal. Values are: 0 No padding 1-31 Number of character delays 10 Line Folding This provides for automatic insertion by the PAD of appropriate format effectors to prevent overprinting at the end of a terminal print line. Values are: 0 No line folding n Character per line before folding, where 1<=n<=255 11 Binary Speed This parameter is set by the PAD when the terminal establishes a physical connection to the network. This allows the remote DTE or terminal user to examine the speed, as determined by the PAD. Values are: 0 110 bps 1 134.5 2 300 3 1200 4 600 5 75 6 150 7 1800 8 200 9 100 10 50 11 75/1200 12 2400 13 4800 14 9600 15 19,200 16 48,000 17 56,000 18 64,000 12 Flow Control of the PAD by the terminal This allows for flow control between the terminal and the PAD. The terminal indicates whether or not it is ready to accept characters from the PAD, via XON and XOFF characters. Values are: 0 No use of XON/XOFF 1 Use XON/XOFF 13 Linefeed Insertion This parameter instructs the PAD to routinely insert a linefeed (LF) character into the data stream following each appearance of a carriage return (CR) character. Values may be OR-ed together: 0 No LF Insertion (TP4 Default) 1 Insert LF after CR on output to the terminal 2 Insert LF after CR on input from the terminal 4 Insert LF after CR on echo to the terminal 14 Linefeed Padding This parameter provides for automatic insertion by the PAD of null character padding after the transmission of a linefeed to the terminal. Values are: 0 No padding 1-15 null characters 15 Editing This parameter enables local editing of text within the PAD before transmission through the network. Note, if editing is enabled, transmission on timers is disabled. Values are: 0 Editing disabled (Default) 1 Editing enabled 16 Character Delete Parameter 16 specifies the editing character which causes the PAD to erase the previous character entered by the terminal. Parameter 16 is only valid if editing is enabled. Default is 127. 17 Line Delete Parameter 17 specifies the editing character which causes the PAD to erase the entire buffer. If data is forwarded on carriage return only, the buffer contains one line at a time. Parameter 17 is only valid if editing is enabled. Default is 24. 18 Line Display Parameter 18 specifies the editing character which causes the PAD to echo the entire buffer to the terminal. Parameter 18 is only valid if editing is enabled. Default is 18.
