Up to now, SRM was only capable of reading 5 lanes through 1 parallel port. More lanes required a second printerport. Most of you did not care about this, because few users have more than 4 lanes, but sometimes it can be handy!

The next version of SRM will support more than 5 lanes with one port, theoretically up to 9 lanes! You might try it with version 2.50: this version also supports this feature (not officially, but it should work).
