USER MANUAL

WINDOWS UTILITY DRIVERS

ACCES provides drivers for use with 16- and 32-bit Windows languages. ACCES32, a 32- bit driver, provides hardware register access when writing software for Windows 95/98/NT. The same hardware level access is provided for 16-bit applications using VBACCES, a 16- bit driver for VisualBASIC 3.0. Both drivers are in the form of a .DLL and sample code is included that demonstrates their use. Together, these files allow you to access the port and main memory space in a fashion similar to BASIC, QuickBASIC, Pascal, C/C++, Assembly, and most other standard languages using the four functions listed below.

To use VBACCES, you must create a .MAK file (File l New Project) similar to the sample provided (or else, modify your existing project file) and include the .GBL file (File Add File). To use ACCES32, refer to the sample code for the language -specific commands for adding the DLL to the project.

InPortb

 

Function:

Reads a byte from a hardware port. Due to limitations of VisualBASIC,

 

the number is returned in an integer.

Declaration: function InPortb(byval address as integer) as integer

InPort

 

Function:

Reads an integer from a hardware port. This function returns the 16-bit

 

value obtained from reading the low byte from address and the high byte

 

from address+1.

Declaration: function InPort(byval address as integer) as integer

OutPortb

 

Function:

Writes the lower eight bits of value to the hardware port at address. This

 

function returns the value output.

Declaration: function OutPortb(byval address as integer, byval

 

value as integer) as integer

OutPort

 

Function:

Writes all 16 bits of value to the hardware port at address. This function

 

returns the value output.

Declaration: function OutPort(byval address as integer, byval value as integer) as integer
