8.6.5 YMODEM Library
Overview
This library is used to transfer files from Windows applications using the YMODEM/bat protocol.
The YMODEM library consists of a group of the following files.
YMODEM.H Header file for system library (for C language)
LibYMOD.LIB YMODEM library for C language (for C language)
YMODEM.DLL Main program of the YMODEM library
Relations between the files are summarized as follows. When developing your application program
with the C language, never fail to link LibYMOD.LIB with the developed source program. This
LibYMOD.LIB will automatically call YMODEM.DLL, which is the main program of the system
library, at each execution of the program. Visual BASIC can directly call this DLL by means of a
declaration.
