CS/2 Netbios Pubs Update and Usage Information


D0065300: NB Configurable Receive Buffer Size plus STO/RTO This DCR (Design Change) is in the cs2nbr00.exe product code CS/2 1.3.1. The documentation was not in CS/2 1.3.1 because this was originally an undocumented feature. Since many customers are now using these start parameters, we are providing the documentation here for your usage and convenience. Update to the NETBIOS REM from 12/15/93 (DCR D0065300): CS2NBR00 start parms. To use these, add the keyword and value and change the REM's "use start parms" flag to "yes". These values get read when the NB REM is started. To have changed values take effect, the REM must be stopped and restarted. STO - NETBIOS send timeout. This value gets set on the NCB.CALL and NCB.LISTEN commands. It then applies to NCB.SEND_W commands for that session. It is in 500 millisecond units, so a value of 10 gives a timeout of 5 seconds. If this timeout occurs on a NCB.SEND, the session is terminated. The default is 30 seconds. RTO - NETBIOS receive timeout. Similar to send timeout. The default is 15 seconds. RBUF - NETBIOS receive buffer size used by the NETBIOS REM. The default is the minimum RBUF size of 670 bytes (RWA headers and a user data size of 512). The maximum size is 65,280 bytes. NM8CHK - Parm to indicate that the REM should check that incoming CALLs have NETBIOS names that are 8 bytes or less. The bytes after the 8th must be blanks. If this start parm is not used, then the REM will not check incoming names to ensure that they are eight bytes or less (the current REM behavior, only the first 8 are used). Whether the check is done or not, the REM will not use more than 8 bytes for a name. Example of start parm in CS2NBR00 (NB REM's) ACB: STO=20 RTO=20 RBUF=1024 NM8CHK=1 Gives: send time out of 10 seconds (20 * .5 secs); receive timeout of 10 seconds; receive buffer size of 1024 bytes; and the 8 bytes name check will be used.
