value effectively leaves the connection permanently open.
status_request:
This can have the value disable or
enable. When it is enabled, the software
sends a status request to the device attached to the terminal server and processes
the reply as follows:
LP_OK (0x30) ocd continues processing.
LP_NO_PAPER (0x31) ocd retries within the limits of the status
timer.
LP_BUSY (0x32) ocd retries within the limits of the status
timer.
LP_OFF_LINE (0x34) ocd retries within the limits of the status
timer.
LP_DATA_ERROR (0x38) ocd retries within the limits of the status
timer.
status_timer:
This defines the time in seconds during which the software waits for the reply to the
status request. If the timer expires, an error message is logged to
/var/adm/syslog and the error is transmitted to the user application.
eight_bit: This can have the value disable or enable. Normally, data bytes processed by
the pty have bit 7 stripped. If eight_bit is enabled, the stripping is disabled. If
eight_bit is disabled, stripping is enabled and bit 7 is stripped. This can also be
achieved by changing the termio structure of the pseudonym using ioctl( ) com-
mands.
tcp_nodelay: This can have the value disable or enable. When it is enabled, data is sent to
the LAN as it is received. It can be disabled if the software is sending packets fas-
ter than the server can accept them.
The default values are:
telnet_mode enable
timing_mark enable
telnet_timer 120
binary_mode disable
open_tries 1500
open_timer 30
close_timer 5
status_request disable
status_timer 30
eight_bit disable
tcp_nodelay enable
WARNINGS
In order to ensure that commands (such as ps) display the correct device file name (that is, the pseu-
donym), all pseudonyms should be placed into the directory /dev/telnet. If pseudonyms are not
specified for placement in this directory, the correct display of device file names with many commands is
not guaranteed.
In addition, in order to ensure that commands (such as
w, passwd, finger, and wall) work correctly,
each pseudonym must be unique in its first 17 characters (including the directory prefix
/dev/telnet/). If pseudonyms are not unique in their first 17 characters, the correct functioning of
many commands is not guaranteed.
