Do you mean it's sending ascii data on an RS232 port? I don't have any software experience with reading serial on RedHat but I do know a little about RS232 and Parallel ports on PCs. The first thing you are going to have to do is find a box that will properly convert the signalling from RS232 to LPT levels. I know that RS232 signal level spec is +12V and -12V on a PC and I think that LPT is +5V and 0V. I do know that if you adapt an RS232 cable directly to an LPT port with no signal conversion between them more often than not you will destroy the LPT port...either way you won't get any data flow because the connectors are wired totally different.
