DRIVER Details
The DRIVER keyword introduces a section of configuration to control the driver program itself:
RUN HIDDEN | VISIBLE
On Windows, this controls the Driver window (independently from the presence of a log file)
• If HIDDEN is specified, then no window or taskbar Icon are displayed.
• If VISBLE is specified, then a normal window is shown on the screen.
• If the item is omitted, then a Taskbar Icon appears, but the window is minimised.
On Linux, RUN VISIBLE causes the Paylink log to be output to stdout.
USE GLOBAL SEGMENT
On Windows only this specifies that shared memory segment, which is used to communicate
with the application, should be in the Global namespace.
This enables IIS to see a normal mode driver, but requires the driver to run with elevated
privilege.
LOGFILE “<Name>” [SIZE <K bytes>]
This specifies that a log file is to be generated.
<Name> is the full path to the desired log file, the “ symbols are compulsory even if there are
no spaces in the name.
<K Bytes> is the maximum size the log file is allowed to reach. If it reaches this size, then it is
renamed with a “.old” extension added and a new file started.
If SIZE is omitted, the maximum size is 128K bytes.
SERIAL [NUMBER} <Paylink Serial>
This is used in multiple Paylink installations, and specifies the serial number of the Paylink
device that this driver is to connect to. (This is also available as a Driver program option.)
