This identifies the character which, when sent from the network to
|
||
the terminal, causes the terminal to resume transmission of
|
||
buffered data. Value may be any character from 1 to 127. Default
|

transmission of buffered data. Value may be any character from 1
|
||
to 127. Default is 19 (21 octal, 13 hex).
|
||
|
||
|
||
*44 Generate Break
|
||
|
||

|
||
parameter.
|
||
|
||
|
||
*45 APP on Break
|
||
|
||
This parameter specified whether or not the PAD transmitted a
|

|
||
longer be used.
|
||
|
||
0 No SET & READ PARAMETERS PAD Message (Default)
|
||
generated on break
|
||

locked, and the PAD had no data to deliver to the terminal. Values
|
||
are:
|
||
|
||
0 Unlock based on timer expiration (Default)
|
||
1 Unlock based on input data content
|
||
|
||
|
||
*47 Input Unlock Timer
|
||
|
||
This archaic parameter specified the time interval that the PAD
|
||
would wait before unlocking the terminal keyboard, if the PAD had
|
||
no data pending delivery to the terminal and parameter 46 was set
|
||
to 0. Values ranged from 0 through 255 multiples of 50 ms (.05
|
||
seconds). Default was 0 seconds.
|
||
|
||
|
||
*48 Input Unlock Character
|
||
|
||
This archaic parameter specified the character which, when appearing
|
||
at the beginning of a data line, caused the PAD to leave the keyboard
|
||
locked at the end of the data line (if there is no data pending
|
||
delivery to the terminal). Value was any character code from 0
|
||
through 127; or 240, which leaves the keyboard locked after all
|
||
characters. Default was 0.
|
||
|
||
|
||
*49 Output Lock Option
|
||
|
||
This archaic parameter specified the action the PAD took when it
|
||
received data for delivery to the terminal, when the keyboard was
|
||
unlocked for input from the terminal. Values are:
|
||
|
||
0 Discard output data
|
||
1 Transmit output after input completion
|
||
2 Transmit output id input idle (Default)
|
||
|
||
|
||
*50 Output Lock Timer
|
||
|
||
This archaic parameter defined the interval between characters
|
||
arriving from the terminal which, when exceeded, caused the PAD
|
||
to lock the keyboard when it had output pending delivery to the
|
||
terminal. Values may range from 0 through 255 multiples of 50 ms
|
||
(.05 seconds). Default was 10 (500ms).
|
||
|
||
|
||
*51 Output Lock Option
|
||
|
||
This archaic parameter specified what action the PAD took after it
|
||
had transmitted all pending data to the terminal. Values are:
|
||
|
||
0 Unlock based on timer (Default)
|
||
1 Unlock based on output completion
|
||
2 Unlock based on output data content
|
||
|
||
|
||
+53 Break Options
|
||
|
||
This allows for a combination of options for handling break signals
|
||
from the terminal. Values may be OR-ed together:
|
||
|
||
0 No options selected (Default)
|
||
1 Interrupt on break
|
||
4 APP on break
|
||
32 Insert on break
|
||
|
||
Note, X.3 parameter 7 should be used instead of this parameter
|
||
|
||
|
||
54 Terminal-to-PAD Flow Control
|
||
|
||
This parameter specifies XON/XOFF control of transmission from the
|
||
network. Values are:
|
||
|
||
0 No Terminal-to-PAD flow control (Default)
|
||
1 Network respects flow control
|
||
|
||
|
||
55 Terminal-to-PAD XON Character
|
||
|
||
This identifies the character which, when sent to the network,
|
||
causes the network to resume the transmission of buffered data.
|
||
Value may be any character code from 1 through 127. Default is 17
|
||
decimal.
|
||
|
||
|
||
56 Terminal-to-PAD XOFF Character
|
||
|
||
This identifies the character which, when sent to the network,
|
||
causes the network to temporarily suspend the transmission of
|
||
buffered data. Value may be any character code from 1 through 127.
|
||
Default is 19.
|
||
|
||
|
||
57 Connection Mode
|
||
|
||
This parameter specifies which level of terminal code conversion
|
||
the PAD is to perform during data transfer mode. Values are:
|
||
|
||
0 Transparent
|
||
1 Real
|
||
2 Virtual (Default)
|
||
|
||
|
||
+58 Connection Escape
|
||
|
||
This parameter specifies whether or not the terminal may escape
|
||
from Data Transfer mode to Network Command mode. Values are:
|
||
|
||
0 Escape not possible
|
||
1 Escape possible (Default)
|
||
|
||
|
||
*59 Flush Output on Break
|
||
|
||
This parameter specified whether or not the PAD transmitted a SET &
|
||
READ PARAMETER PAD Message to the Host and began discarding output
|
||
to the terminal when a break signal was received from the terminal.
|
||
Rather than using this parameter set X.3 parameter 7 to 21
|
||
(decimal).
|
||
|
||
0 No SET & READ PARAMETERS PAD Message (Default)
|
||
sent and no output flushed
|
||
|
||
1 SET & READ PARAMETERS PAD Message sent and output
|
||
to the terminal
|
||
|
||
|
||
60 Delayed Echo
|
||
|
||
This parameter identified whether echo from the PAD to the terminal
|
||
will occur immediately or whether it will be delayed to appear
|
||
between data from incoming packets. If 60:1, then once the PAD has
|
||
begun processing an incoming packet, it will buffer echo characters
|
||
until it completes the packet. At that point, it will transmit all
|
||
buffered echo characters back to the terminal before processing the
|
||
next incoming packet. Values are:
|
||
|
||
0 Echo immediately (Default)
|
||
1 Delay echo to occur between incoming packets
|
||
|
||
|
||
63 Eight-bit Transparency
|
||
|
||
This parameter identifies whether the terminal uses the eighth
|
||
(most significant) bit for data or as a parity bit. Note, if
|
||
Telenet parameter 57:2, this parameter cannot be set to zero.
|
||
Values are:
|
||
|
||
0 No parity, eight-bit transparency
|
||
1 Parity required (Default)
|
||
|
||
|
||
64 Early ACK
|
||
|
||
This parameter specifies whether or not the PAD for terminal
|
||
support should acknowledge data packets received for the terminal
|
||
prior to transmitting the packets (in the form of a character
|
||
stream) to the terminal. Values are:
|
||
|
||
0 Acknowledge data packets after transmission
|
||
to the terminal (Default)
|
||
|
||
1-7 Acknowledge data packets 1-7 packets prior to
|
||
transmission to the terminal
|
||
|
||
Note: *Extreme Caution* should be exercised when modifying this
|
||
parameter. The increased "artificial window" size does not
|
||
guarantee packet delivery to the terminal. Large amounts of
|
||
data could be lost from any form of network disconnect.
|
||
Values of 5 or greater should never be used.
|
||
|
||
|
||
65 M-bit handling
|
||
|
||
This parameter specifies whether the terminal PAD will set the M-bit
|
||
on all full packets, on certain full packets, or on packets. Values
|
||
are:
|
||
|
||
0 M-bit is always zero
|
||
1 M-bit is set to one for certain full packets
|
||
3 M-bit is set to one in all full packets (Default)
|
||
|
||
If parameter 65:1, the PAD will set the M-bit on all full packets
|
||
except where the last user-entered character is a data-forwarding
|
||
character, as defined by X.3 parameter 3 (Transmit Mask). If,
|
||
however, the final character in the packet is a carriage return and
|
||
X.3 parameter 13 causes a line feed insertion following the carriage
|
||
return and X.3 parameter 3 marks carriage return as a data-forwarding
|
||
character, then the M-bit will be set to 1. The PAD will then
|
||
transmit a second packet, with M-bit set to 0, containing only a
|
||
line feed character.
|
||
|
||
If, after sending a packet with M-bit set to one, the PAD must send
|
||
a data-qualified packet (Q-bit=1), this is considered a data-
|
||
forwarding condition. Thus, the PAD will send a data packet with
|
||
M-bit = 0 containing the characters currently in its buffer. If
|
||
the buffer is empty the PAD will send an empty packet with M-bit = 0.
|
||
This prevents a protocol violation.
|
||
|
||
|
||
66 Defer Processing of User Input
|
||
|
||
This parameter instructs the PAD to halt processing of user input
|
||
data and buffer the data (to a maximum of 32-64 characters). Upon
|
||
disconnect, parameter 66 is rest and processing of user data resumes.
|
||
If the disconnect triggers a reselection (e.g., forwarding of the
|
||
call by TAMS), the buffered data is sent to the new called DTE
|
||
Otherwise, or if reselection fails, the data is interpreted by the
|
||
PAD as a command during command mode. Values are
|
||
|
||
0 Process user input normally (Default)
|
||
1 Defer processing of user input data
|
||
|
||
67 ESP Packetizing Option
|
||
|
||
This parameter specifies whether accumulated data is to be packet-
|
||
izied when the Escape Sequence Initiator is received (i.e., before
|
||
the Escape Sequence) and when the Escape Sequence is completed.
|
||
Values are:
|
||
|
||
Packetize Packetize
|
||
Before After
|
||
|
||
0 No No (Default)
|
||
1 No Yes
|
||
2 Yes No
|
||
3 Yes Yes
|
||
|
||
|
||
68 Escape Sequence Timer
|
||
|
||
This parameter specifies the maximum idle time allowed before ESP
|
||
processing expires. Values range from zero through 255 and
|
||
represent 50 ms intervals. Resolution of the timer is zero to
|
||
minus 50 ms (e.g., a value of 2 represents 50ms < timer < 100ms).
|
||
Default is zero.
|
||
|
||
|
||
69 Escape Sequence Maximum Length
|
||
|
||
This parameter specifies the maximum number of characters that may
|
||
be contained in an Escape Sequence, including the Escape Sequence
|
||
Initiator. A value of zero disables parameter 69 and the maximum
|
||
Escape Sequence is 128 characters. Default is zero and values
|
||
greater than 127 are not allowed.
|
||
|
||
|
||
70 Escape Sequence Initiator
|
||
|
||
This parameter specifies the seven-bit representation of the Escape
|
||
Sequence Initiator character (values 1-127). The default value of
|
||
zero disables Escape Sequence Processing altogether.
|
||
|
||
|
||
71 Parameter Reset on Disconnect
|
||
|
||
This parameter specifies the manner in which parameters are to be
|
||
treated upon disconnect. Values are:
|
||
|
||
0 Reset ITIs to their initial values (Default)
|
||
1 Do not reset ITIs, except for reselect-related
|
||
parameters (66 and 71)
|
||
2 Do not reset ITIs, except set 66:0 and 71:1
|
||
3 Do not reset ITIs, except set 66:0
|
||
|
||
Value 1 makes parameter 71 a "one-shot" parameter, this is it
|
||
clears itself after being invoked once. Value 2 is a "two-shot"
|
||
value and value 3 leaves parameter 71 active until explicitly
|
||
reset.
