with all MR350MKII? input/output devices. All detailed calling convention and
source code are listed behind each BIOS/DOS call in Chapter 3. For easily using
this library, Unitech also provide sample program (350TEST.C) to help user to use
it. So, user can directly modify this sample program. All of those files are stored on
sub-directory "LIB" of DEMO disk.
5.2. Programming communication program
In Chapter 4, there are details description about Multi-Protocol between
MR350MKII and Host computer. Users can follow this protocol to develop
communication program or integrate them into their application program. But it
seem that it is a little difficult for most user to implement communication program
according specification of communication protocol. So, Unitech provide
communication utility library to help user develop their application program without
know detail communication protocol. In our demo disk, it includes DOS version and
Windows version communication program, communication library and its sample
program.
In DOS platform, we provide a C library (485LIB.C and SLIB.OBJ) for user to
develop their DOS base communication program. We also provide a sample
program 485COM.C for fully using 485LIB.C, so users can directly modify this
program or porting it to your application program. All of those files are stored on
sub-directory "DOSCOM" of DEMO disk
In Windows platform, we provide 16bits/32bits communication DLL for user to
develop their Wondows communication program or intergate communication
function into their application program. User can call this DLL from his Visual
C/C++, Visual Basic or Delphi. All of those files are stored on sub-directory DLL
of DEMO disk.
