Parallel Port

I have two lines in the following files that I would like to know more about.
1)  In autoexec.bat:  set ssi_act=100,100,200

2) In system.ini, under [386Enh]:  ssi_lpt=1

I believe they have something to do with the parallel port, but I would like to know exactly what they are and do.

Do you have any programs or hardware which have those specific "Initials/abbreviations" in them?  or their manufacturer.  Such as maybe..."Silicon Software Imagery" -> which might be a Graphics program.  Do you have a scanner?

Seems like parameters for a security key.

Look at this site : (Technical Support)

SSI_ACT=x,y,z where x,y,z are integers from 1-1000

         This setting will add delays between calls to the key in an effort to allow the key to work properly on faster machines. This setting should be set in the
         AUTOEXEC.BAT as:
         SET SSI_ACT=x,y,z
         or for Windows NT, should be set as an environment variable in the CONTROL PANEL/System/Envrionment setting.

ssi_lpt=1 is the port on which the security key is installed.

Sounds kind of like a dongle is installed in that respect, for it to be a security key....
