The main network settings are located in the [NETKERN] section of the initialization INI file (the default values defined in parentheses):
CANCELONDISCONNECT = 1 — If 0, the server tries to reconnect to the client in case of a disconnect after receiving (sending) an RPC request
CRYPT = 1 — encryption when sending
FILEMANAGERPATH = u: — A basic path of file functions (always added to the file name). The * path is processed separately.
IGNOREERRORSFROMSERVER = 1 — If set to 0, the stack of error codes passed from the server in case of an execution error on the server will be saved in the error file.
LOADALLPROTOCOLS = 1 — If 0, exits RPCInitEx at the first loaded protocol, the rest are loaded asynchronously during the working process. If 1, it does not exit until it loads all the protocols.
MAXSENDRETRYS (2 — CANCELONDISCONNECT) — A number of attempts to send a data block
MAXBLOCKSIZE = 20000000 – Maximum packet size (for example, that of the RPC procedure returned data). It must be the same on both the client and the server.
MINPACKSIZE = 15000 – Minimum packet size. In the case of SLOWCONNECT=1 in the protocol settings of one side, a value of 10 times less is used.
MINPACKDELTA = 1000 – Minimum size of reduction during data packing. In the case of SLOWCONNECT=1 in the protocol settings of one side, a value of 10 times less is used.
PROTOCOLS = PROTOCOL\*. DLL — Masks for searching driver DLL files via ";". If the server and the cash register are installed on one and the same device, use localnet.dll.
RETRYRECEIVE = not CANCELONDISCONNECT — Wait for the reconnect to the client to continue receiving the data packet.
ROUTERCOUNT = 2 – The number of routing tasks.
TESTMESSAGES = 0 — If 1, outputs a network operations log in the debug log file
to the debug file ALLSENDLOG = "" – If the value is not empty, then this should be the directory (with the final "\") where the files with the sent data will be stored.
TIMEOUT = (30000/180000) — ms. — handshake wait timeout and wait timeout of connection send queue (there are different tasks in the queue that use the same connection). If SLOWCONNECT=1 is set in the protocol settings, the queue timeout will be at least 180000, even if a lower value is set.

The driver reads the [TCPSOC] section of the record from the INI file (default values defined in parentheses):
ASYNCHCONNECT = 1 — try to connect asynchronously
CHECKSELFNAME = 0 — try to find a self name during initialization (to avoid duplication).
KEEPALIVE = 1 — send keepalive requests
LISTEN = 1 — Wait for connections from others
MAXBUFFER = 65280 — the maximum size of data sent by a single command
SLOWCONNECT = 0 – if 1, changes the default values for MAXBUFFER (4096), TIMEOUT (20000). In addition, the pfSlowConnect driver type flag is set, which uses other timeouts inside NetKern.
DNSFILE = tcpdns.txt – DNS name file.
Format of the entry record in the name decryption file:
Name Name address [:port]
Address – — a dot — -separated Internet address or a computer name on in the local network or DNS name
The port is Port — either decimal or hexadecimal (preceded by a $signthe $ sign). By default, port = PORT.
For example, for the names the AA and CCCC names:
AA 198.154.196.105:5150
CC COMPUTER1:5155
DNSSECTION (TCPDNS) — a section in the same file that contains name decryptions.
Format of the entry record in the name decryption section:
...
[TCPDNS]
AA=198.154.196.105:5150
CC=198.154.196.105:5155
PORT = 5150 – – the port number for incoming connections. If port=5150 and there is an error that the port is busy, the number will increase by 1, etc.
PRIORITY = 50 – – the driver priority of the driver compared to the others (the smaller numbers are viewed first)
TIMEOUT = 4000 – – timeout for the operation of send/receive blocks MAXBUFFER MAXBUFFER blocks sending/receiving or connect with ASYNCHCONNECT=1
USEINTERNETDNS =0 – – if 1, the driver will try to find the DNS name on the Internet, with 1 ignored SENDTO255IPSENDTO255IP is ignored
RECEIVELOG = "name" – the file name of the file for received data logging revenues
SENDLOG = "name" – – the name of the file to log shipmentsfile name for sent data logging
UDP_BROADCAST_PORT = 5160 – – the port number to for messages exchange messages (including broadcast) to determine the address by name, must be the same across the entire network
| Note |
|---|
...
| To disable broadcast messages from any server, set UDP_BROADCAST_PORT = 0 |
SERVERNODELAY = 0 — with a value of 1 for incoming connections if 1, disables the Nagle algorithm for incoming connections, which leads to faster response, but may lead to a narrowing of the channel narrowing.
CLIENTNODELAY = 0 — the same as SERVERNODELAY, but for outgoing connections
WAITBEFORECLOSE = 0 — at if 1, it will wait for the completion of network operations when the connection is programmatically terminatedwaits for the network operations completion in case of program disconnection.
SENDTO255IP = 0 — at 1 if it is impossible to find out the address if 1, in case the address cannot be found by name, it tries to reach all 254 addresses of the subnet (USEINTERNETDNS must be 0)

The driver reads reads the [NB] section from the ini INI file, writes records (default values defined in parentheses, default values):
TIMEOUT=15000 — timeout of network operations in milliseconds
Listen=1 — whether to "listen" «listen» — wait for connection. Only for nb.dll
Recommendations when using a slow communication channel
If a low — -speed communication channel is used, then the following parameters should be configured: ShortTimeout, LongTimeout both both for the directory reference server (REFSERVER — the REFSERVER is the main section) and for the manager stations (REFEDIT is the main section).
CollFileCache for for the manager station, for storing directories references in files and synchronizing only changed collections (REFEDIT is the main section).
