SSH Reference Manual

OTX (open table index)=2. Each opener has an entry in the open table. The unnamed process running on node
\CENTDIV with cpu,pin=1,50 has opened the application with terminal name #COMMAND.COMMAND as
file number 3.
The #COMMAND.COMMAND terminal name indicates a STNCOM requester.
The program is running under group,user=255,255 (SUPER.SUPER) from object program file name
$SYSTEM.SYSTEM.STNCOM with home terminal $OSP.
Note: the LISTOPENS command can generate a very long response.
MAX_OPENERS <n>
Defines the maximum number of application openers of a window. <n> may be in the range 1-512 and defaults to 32.
Prior to STN version B22, the allowed range was 1-64. Any open attempts beyond the maximum will be rejected with
feopenstop 61. This feature prevents an ill-behaved application from monopolizing STN resources. Larger values of
MAX_OPENERS may require an increase in PARAM OPEN^TABLE^SIZE, especially when many windows are
active.
MAX_OUTQ <n>
MAX_OUTQ defines the maximum number of messages queued for a window. Default 0 (zero) means no maximum.
Allowable range is 0-50. If the limit is exceeded (by an unusual application), an EMS message is generated and the
session is terminated. Use only on recommendation of HP support staff.
NBOT Y|N
STN supports Non-Blocking OSS Terminals (NBOT) which is used by the Posix system call select(). The NBOT
command can be used to disable this feature. The default "Y" enables NBOT by setting bit<11> in the misc flags field in
replies to Posix open messages. NBOT N clears bit<11> to indicate select() is not supported, to be compatible with STN
releases prior to B08.
NBOT_TIMEOUT <seconds>
NBOT_TIMEOUT controls error recovery for NBOT. The default setting is 8 (seconds). When NBOT=Y, if STN cannot
open or writeread a select ready message to Terminal Helper ($ZTTnn), after NBOT_TIMEOUT seconds STN will send
a Posix SIGQUIT (control-\) to the application. Setting NBOT_TIMEOUT to 0 (zero) disables the feature, usually
meaning the application will hang until Terminal Helper finally responds. The signal can occur promptly after
NBOT_TIMEOUT expires, but can be delayed as much as 60 seconds.
NEGOT_TIMEOUT <seconds>
This is the time allowed for IAC negotiations to complete, defaulting to 20 seconds. If the timeout expires, usually due to
the TN6530 client improperly configured with line mode disabled, an STN50 message is displayed for 10 seconds, then
the session is terminated. <seconds> can be in the range from 1 to 120.
OBEY <edit-file-name>
OBEY processes STNCOM commands from an EDIT format file.
<edit-file-name> specifies the EDIT file in which the commands are listed. Commands can be nested up to six levels
deep.
