NEGOTIATE and NONEGOTIATE

specify the action to be taken when a call request with a value different from the default

value for PKTSIZE, L3WINDOW, or THRUPUT has been received.

If PKTSIZE, L3WINDOW, or THRUPUT has been defined as NEGOTIATE, the

subdevice will accept a call containing a value that differs from the default value.

If L3WINDOW or THRUPUT has been defined as NONEGOTIATE, the subdevice will

accept a call containing a different value, but the subdevice uses the default value.

If PKTSIZE has been defined as NONEGOTIATE, the subdevice will reject a call

containing a value that differs from the default value for PKTSIZE.

The default specification is NONEGOTIATE for PKTSIZE, L3WINDOW, and

THRUPUT.

NETID

specifies the method of determining network-specific requirements, such as the port

number for incoming calls. The NETID depends upon the X.25 network type. For

details about NETID and REMOTENET, see Appendix D, Using the NETID Modifier.

NULLFILL

is valid only for subdevices configured with the ITI Protocol. This modifier indicates the

mode-setting control sequence sent to the terminal. ON is used for terminals using

microcode revision C and earlier. The default NULLFILL OFF is for terminals using

more current microcode revisions. The control sequences are as follows:

NULLFILL ON: Conversation Mode = EOT NUL SOH “C” ETX

Page Mode = EOT NUL SOH “B” ETX

Note. If you configure a PVC incorrectly with the NEGOTIATE attribute, X25AM will not issue

an error message. You can, for example, specify the NEGOTIATE PKTSIZE attribute for a PVC

without having the X25AM subsystem issue an error message. However, optional user facilities

(per call facilities) such as NEGOTIATE PKTSIZE have no effect on the PVC subdevices.
