pport program unknown option
 

Hi everybody,

i found a software called pport on sourceforge.net. I´d like to use some kind of program to easily set dtr or rts high/low to get a signal, so i tried pport. It returns "unknown option" when i use -p serial. Has anyone any experience of the program?

i have tried to compile it with correct --with-serial option, but with no result...

Where did you find this option documented? The README describes using pport only with the parallel port. The help shown after building does not show it either. The man page shows "pport -p serial -s none", but also points out you need to be superuser when running this. Are you?

The ChangeLog shows the serial port pins were implemented in version 0.6.5 however a quick look through the source code did not have -p as an option. The --with-serial option defines the default serial port memory address. Can we assume that without the -p option by selecting a serial port pin i.e. dtr or rts pport will use the default serial port address?

PS: After reviewing the ChangeLog again the port option was removed in version 0.6.6.
