No, I was using cat directly to the port and the file was a non-postscript!

*** Please comment for those of you who knows about stuff like this:
Would it be a good idea (hack!) to do something like this somewhere in the
initialization of IrCOMM (ircomm_tty.c, ircomm_tty_open()?):
tty->termios->c_iflag = 0;
tty->termios->c_oflag = 0;
.. to force the ldisc into "raw" mode by default which is what we usually
want for IrCOMM and IrLPT? That way, we will not need to twiddle with
printcap etc.
