DP839EB-ATS SONIC Packet Driver for PC/TCP by FTP Software
INTRODUCTION
This is a program listing for a driver for the DP839EB-ATS SONIC Ethernet Adapter. This driver enables the DP839EB- ATS to operate with a TCP/IP software package from FTP Software Inc. called PC/TCP. This driver is written to ver- sion 2.0x of this software package.
This software program listing is provided primarily as a pro- gramming example for writing software for the DP83932 Systems Oriented Network Interface Controller. This driver is written in Microsoft C 5.1 and Microsoft Assembler 5.1.
Since the bulk of the software is written in C, the concepts provided are easily portable to other environments.
This example driver was not written to achieve optimum per- formance with PC/TCP, but primarily to show how the SON- IC Controller can be programmed.
This software does not make use of higher performance upper level features, and performance is limited by this.
The driver is listed by modules in the order listed below.
1. pktdrv.c 6. sonic.h 2. far.c 7. isrlib.asm 3. isr.c 8. pktint.asm
4. sonic.c 9. pktdrv.mak (make file) 5. pktdrv.h
