New Features

printer_crlf

Epson printers monitor pin 14 of the parallel port to decide how to

handle CR. If pin 14 is high, the printer performs a CR. If pin 14 is

low, the printerperforms aCR/LF. The default value is Yand enables

the converting of <CR> to <CR><LF>. The value of Ndisables the

parameter so the printer does not add a <LF>.

Telnet Connectivity to Parallel Ports

Parallel ports now appear on the network as Annex TCP ports 5901-

5999 and 7901-7999. This means that rtelnet can access the parallel

ports; aprint is no longer necessary to use the parallel ports.

Forwarding Broadcasts

Thisreleaseadds theAnnexparameter ip_forward_broadcast.If this

parameter is set to Y, the Annex forwards Network directed IP

broadcasts to installed interfaces of the same network.

Default Domain

This release adds the keyword domain to the gateways file, and

modifies the output of the CLI hosts command. The new gateways

keyword usage is:

domain search <path> <path...>

This form adds a network domain to the DNS search path. The

given paths are decomposed into higher-level names, and all of

the forms are added. For example, mynet.city.company.com

decomposes into mynet.city.company.com, city.company.com

andcompany.com. To preventthis, you canquote a portion of the

path that should not be decomposed. For example,

this."that.theother.edu" decomposes into this.that.theother.edu

and that.theother.edu. When these paths are added, the list is

checked for duplicate entries (case is not significant), and the

duplicates are silently ignored.

domain default <path>

The second form sets the default search path. This path should be

set after all search paths have been added. The Annex will

propagatethispathto thetopofthesearchlistandremoveitfrom

all of the hosts entries.

Thenewhostsoutputisinresponsetothehosts-noption.Inaddition

to displaying the name server data, this option now also displays the

default domain and the domain search list contents.

The Annex still does a reverse address query for its domain name,

and if a valid response is received, the Annex overrides the contents

ofthegatewaysfile,setsitsdefaultdomainandaddsthedecomposed

response to the search list.

ACP to Work with NIS

This release adds simple support for host passwd and shadow file

reading routines to erpcd. These can be selected by the use of the

NATIVEPASSWD and NATIVESHADOW flags in src/erpcd/

Makefile.

Support for 57.6Kbps

The 57600 speed will be supported only in new hardware platform

with fast octart.

do_compression and allow_compression

The slip_do_compression and slip_allow_compression parameters

are renamed to do_compression and allow_compression,

respectively. There is no change to their meaning for SLIP. The

allow_compression parameter now also applies to PPP. If

allow_compression is enabled, the Annex always requests for

compression and always accepts requests for compression. If

allow_compression is disabled, the Annex never requests for

compression, and always rejects requests for compression. The

do_compression parameter is not used for PPP.

The default value for allow_compression isN. Be sure to set this to Y

to negotiate for VJ compression.

Bootp over SLIP Lines

Both SLIP or PPP listen for any BOOTP packets sent by the remote

device that are addressed to either the Annex address(es) [unlikely]

or 0.0.0.0 or 255.255.255.255 [likely]. It then formulates a response

based upon the na parameters and the input packet by examining

each field. If the Server Name field is not null, the Annex tries to

resolve it as a host name. If this succeeds, the Annex fills in some

reasonable IP addresses in the fields and forwards the packet to that

host rather than respond by itself.

DSR Signal

TheuseofDCDandDSRsignalshasbeensplitacrosstwoparameters:

need_dsrandcontrol_lines.Iftheparameterneed_dsrissettoY,DSR

must be asserted to establish a connection on a port. If the parameter

control_lines includes modem_control, that is, the control_lines

parameter is set to both or modem_control, DCD must be asserted

to establish a connection. Separating control of these two signals

provides more flexibility in the use of modem signals.

New Value for output_flow_control

The NA per-port parameter output_flow_control allows the new

value both. This setting (if control_lines is set to flow_control or to

both) enables both in-band (XON/XOFF) and out-of-band (CTS/

RTS) flow control on the Annex III and Micro Annex CD180 serial

communicationschip.Thesemethodsofflowcontrolareindependent

and have no overhead since they are handled by the CD180's

hardware rather than in software.

Setting output_flow_control to both enables both of these flow

control methods by default. It is then up to the user (via stty), or to

TELNET or rlogin protocol to disable the XON/XOFF portion of the

flowcontroliftheremotemodemis capableof out-of-band signaling,

and thus does not need the in-band flow control.

Since the standard character MIB doesn't support both forms of flow

control at the same time, you can't currently set this optionvia SNMP,

and a port with output_flow_control=both will lie to the host and

say it has hardware flow control enabled when queried via SNMP.

TCP keepalive Timers

Threenew tcp_keepaliveparametershavebeenaddedfortheAnnex,

ports and printer. The Annex parameter is the default for all TCP

connections to or from the Annex. The default setting is 120 minutes

(per RFC specifications). It is settable from 1 to 255 minutes. This

parameter is read only on boot-up, so you need to reboot the Annex

if you want to change it. The port parameter is the default for TCP

connections to or from a given port. If it is set to zero, it defaults to

the value of the annex tcp_keepalive parameter.

The printer parameter is the default for TCP connections to a given

printer port. If it is set to zero, it defaults to the value of the annex

tcp_keepalive parameter.

The Annex also does 10 retries at 75 second intervals. So this time

must be added to the tcp_keepalivesetting. Forexample, if the timer

is set to 5 (5 seconds), the maximum time would be approximately

17.5 minutes.

Supported Platforms

TheDistributionmediacontainsbinaryfilesformostofthesupported

platforms. When the script detects that there are binary files for the

host operating system, it gives you the option of installing the binary

files or loading the source code and compiling the software at a later

time. If there are no binary files available, the script loads the source

code and uses an available compiler on the host system to build the

image. If the script does not identify a compiler on your system, it

ends the installation session.

Annex Communications Server R7.1B and Annex Host Tools R14.2 Release Notes

The operating system versions supported by Annex and the binary

files that are provided on the distribution media are shown in Table 1.

Known Problems

Self-boot Annexes

Aself-boot Annex does not correctly load its image into flash from an

Annex boot server (another Annex). The Annex correctly loads its

image into flash from any other host, and the Annex correctly boots

from an Annex boot server.

R7.1 can not fit into half megabyte of FLASH in self-boot units.

Other Limitations

The NA and Admin command set port speed 57600 produces an

erroneous return when the hardware does not support that speed.

Admin produces invalid structure for parameter :speed: 7. NA

produces Netadm error: erpc abort; invalid parameter value.

The parameter need_dsr is ignored for SLIP and PPP lines.

The Annex ignores parameters after rs232AsyncPortAutobaud that

are contained within the same SNMP Set request. The work-around

isto insurethatthers232AsyncPortAutobaudset requestis attheend

of the set request packet or is alone in the set request.

Problems Resolved with this Release

SPR 11150 The acp_logfile is now year 2000 compliant.

The year 2000 is now displayed as "00" rather than "100".

If you are not installing on one of the supported host

platforms and you use the acp_logfile for accounting

purposes, you should be aware that after 991231 (which

represents 1999/12/31) midnight, the entry in the

acp_logfile will appear as 1000101 instead of 000101. If

youhavescriptsthatusethisinformationforaccounting,

you need to modify those scripts to handle this properly.

SPR.9576 Aprint now works properly.
