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() commands.

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 faster

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.
