Virtual UART/FOSSIL Driver Configuration
The sbbsexec.ini file is used to configure the behavior of the kernel mode component of Synchronet FOSSIL and Virtual UART driver for Windows NT-based operating systems (all modern versions of Windows): sbbsexec.dll.
Location
The default sbbsexec.ini file is located in your Synchronet exec directory. If there is another sbbsexec.ini file in the startup directory of the program to be executed (e.g. xtrn/doorgame/sbbsexec.ini), that file will be loaded after exec/sbbsexec.ini, over-riding only those values specified in the second file.
The standard alternate INI filenaming is also supported.
Root Section
These values may be be overridden in a program-specific section named after the program to be executed (e.g. [DSZ] for dsz.exe).
LogLevel
Default: Warning
Possible Values: Emergency, Alert, Critical, Error, Warning, Notice, Informational, Debugging
This key determines the minimum severity of messages from sbbsexec.dll that will be sent to the system debug log.
You can use software such as DebugView to view the log output from sbbsexec.dll.
Debug
Default: false
Possible Values: true or false
CanDisconnect
Default: True
Possible Values: true or false
This key determines whether the program will be allowed to disconnect the user.
YieldInterval
Default: 1.0
Possible Values: 0 and up, fractional values are supported (e.g. 0.5, 1.25, etc.)
Interval of time-slice yield, in milliseconds (fractions supported): Lower numbers result in more frequent yields, reducing CPU utilization and possibly reducing performance/responsiveness while higher numbers can result in fewer yields, increasing CPU utilization (possibly taxing the system) and increasing performance/responsiveness.
This number may need to be “tuned” on a per-program/system basis.
Set to 0 to disable yielding.
[UART] Section
Virtualize
Default: true
Possible Values: true or false
ComPort
Default: 1
Possible Values: 1-4
IRQ
Default: depends on ComPort value
Address
Default: depends on ComPort value
