<i> &gt; &gt;&gt; Newbie-me would say that the printer port would be /dev/ttyS1, as</i><br>
<i> &gt; &gt;&gt; this port has been used successfully to activate a printer in the</i><br>
<i> &gt; &gt;&gt; past. Is there a method to determine this address in hexadecimal</i><br>
<i> &gt; &gt;&gt; form?</i><br>
<p>
<i> &gt;Hmmm... I think that the original qcams were made for Mac and for its</i><br>
<i> &gt;serial ports and I am pretty sure that there isn't any sort of</i><br>
<i> &gt;parallel port on the thing. Looking at the owner's manual...</i><br>
<i> &gt;nope.. just serial.</i><br>
<i> &gt;</i><br>
<i> &gt;Also, no such beast, BIOS on an Apple box. dmesg reveals nothing,</i><br>
<i> &gt;however...</i><br>
<p>
Looks like you have the Mac version of the QuickCam, which is indeed a<br>
serial device, of sorts. The qcam driver is for the PC version which<br>
is a parallel port device, and the driver directly flips bits on the<br>
parallel port, which is why it needs the port address. So, I'd say<br>
you're kind of out of luck from that perspective.<br>
<p>
feature of the Mac serial port, whereby the Mac could clock data<br>
in/out of the port at some high rate, like 1Mbps or so, which is<br>
why the Mac version couldn't be used on a PC (and hence no x86-linux<br>
driver for the Mac version, that I ever heard of).<br>
