TSP^TCPIP^BUF^SIZE

PARAM TSP^TCPIP^BUF^SIZE [

buffer-size

]

TSP^TCPIP^BUF^SIZE

This parameter specifies the size (in bytes) of a dedicated OSI/TS buffer used for

receiving and storing incoming data on each TCP/IP connection (subdevice).

It is used by the calling and responding sides of a connection. This buffer is

allocated during connection establishment and is deallocated after connection

release.

If you use this parameter, the specified buffer size will be the same for all

connections on a particular TSP process. If you don't use this parameter, the

buffer size will vary for each connection( the default value).

Value: Any 16-bit number up to 32000 can be specified; larger numbers are

truncated to 32000. A number less than the TPDU size may cause

performance degradation due to an increase in interprocess

communication (IPC) messages between the TSP and the TCP/IP

process. Larger values use more memory and limit the maximum

number of concurrent connections allowed.

Default: The default is the lesser of:

1. The configured TPDU size (not the negotiated TPDU size), plus

four bytes (for the size of the transport packet header).

2. The size of the internal receive buffer of the TCP/IP process (the

default is 2048).

TSP^TCPIP^OOB

PARAM TSP^TCPIP^OOB [ ON | OFF ]

TSP^TCPIP^OOB

This parameter specifies whether TSP should use the TCP/IP out-of-band (OOB)

data feature when sending expedited data TPDUs. It controls whether to use

network expedited data when using RFC-1006. This parameter controls outgoing

TPDUs only. Incoming ED-TPDUs are received as normal network data, or as

OOB data, regardless of the setting of this parameter.

Value: ON | OFF

Default: ON (Currently, implementor's agreements have not chosen a default

value.)
