Optimizing the GSM for Network Operation
There are two parameters in the [GEFNDIS] section of PROTOCOL.INI which can be
adjusted to optimize the operation of your GSM. These parameters are described below.
Note
Only experienced network personnel should change the values of these
parameters. Setting the parameters to values other than the defaults
could cause unpredictable operation of the GSM.
NUM_RX_BUFS Number of RX frame buffers. This is usually the number of simulta-
neous messages that can be received and processed by the GSM. Defaults to 8 buff-
ers of size specified in MAX_RX_SIZE. This parameter may be increased to handle
additional test frame processing or network station management responses. This
parameter can be decreased to free up PC memory usage.
MAX_RX_SIZE Maximum RX frame buffer size. This is the largest frame which may
be received by the GSM. Incoming data frames which exceed this size will be ignored. A
zero length response is returned when an incoming test frame is received which exceeds
this size. Defaults to 560 bytes for Network GSM use. This appendix shows prototypes
for the DOS system files, CONFIG.SYS, AUTOEXEC.BAT, and PROTOCOL.INI, for each
type of 802.3/Ethernet Interface supported by the GSM.
Note
Also, at the end of the appendix is a section on optimizing the GSM by
adjusting parameters in the [GEFNDIS] section of the PROTOCOL.INI
file.
