Two types of device files are created by the VSPDL:
| • | /dev/vspsn are virtual serial port device files (n is the port number, so actual names look like this: /vsps0, /vsps1, etc.). These are the files that your "serial" application should open for input/output |
| • | /dev/vspdn or /dev/vsp/vspdn (depending on your LINUX kernel version) are system files created by the VSPDL for its internal needs (n is the port number, so actual names look like this: /vsps0, /vsps1, etc.). Do not attempt to access these files. |
