DP839EB-ATS SONIC Packet Driver for PC/TCP by FTP Software AN-748 National Semiconductor DP839EB-ATS SONIC Application Note 748 Packet Driver for PC/TCP January 1991 by FTP Software INTRODUCTION This is a program listing for a driver for the DP839EB-ATS This software does not make use of higher performance SONIC Ethernet Adapter. This driver enables the DP839EB- upper level features, and performance is limited by this. ATS to operate with a TCP/IP software package from FTP The driver is listed by modules in the order listed below. Software Inc. called PC/TCP. This driver is written to ver- 1. pktdrv.c 6. sonic.h sion 2.0x of this software package. 2. far.c 7. isrlib.asm This software program listing is provided primarily as a pro- gramming example for writing software for the DP83932 3. isr.c 8. pktint.asm Systems Oriented Network Interface Controller. This driver 4. sonic.c 9. pktdrv.mak (make file) is written in Microsoft C 5.1 and Microsoft Assembler 5.1. 5. pktdrv.h 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.
