it, however when I attempt to run the script I get this

I am really stumped, it all looks good to me (except of course that it
doesn't work :-(  !, I have trouble shot everything I can think of, I would
really appreciate any pointers on where to look next.  If you need my system
specs, they're listed below.

Thanks,

I've been messing with this for 3 days now, and I'm not really sure where to go now.&nbsp; I'm still fairly new to linux so please excuse any ignorance :) I recently upgraded my mythbox to Knoppmyth R5D1, was previously running R5C7 and R5A26.&nbsp; The script used to work fine under R5A26 (and I believe R5C7 also) but for some reason will not work since the upgrade to R5D1.&nbsp; 
 I have noted other people having this problem with either Knoppmyth or FC4, a couple of which can be found here: <a href="http://www.pvrweb.com//bbs-old/viewtopic.php?t=33515">http://www.pvrweb.com//bbs-old/viewtopic.php?t=33515
</a> <a href="http://mysettopbox.tv/phpBB2/viewtopic.php?p=16081">http://mysettopbox.tv/phpBB2/viewtopic.php?p=16081</a> Okay, here is what I have done to date, Followed the howto here to install dct-channel, (basically, I upgraded Knoppmyth R5D1 to MythTV 
0.20 so the paths were invalid and so downloaded the contrib directory from source instead, everything else was basically the same): <a href="http://www.knoppmythwiki.org/index.php?page=MotorolaDct2000">http://www.knoppmythwiki.org/index.php?page=MotorolaDct2000
</a> The cable box works and the serial port is enabled (just verified today by hooking up to my WinXP box and using the DCT.exe in use by SageTV users, channels change just fine), likewise the cable is (DB9 straight through) okay also, verified by using with the above method and also a voltmeter.
 The serial port on the mythbox (ttyS0) appears to be communicating, verified by copying a file to /dev/ttyS0 and reading a positive voltage on pin 4 (DTR). So, all the hardware seems to be okay. Now for the OS.
 dmesg | grep ttyS returns this serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A&nbsp; (*note* ttyS1 was giving a error &quot;
ttyS1: LSR safety check engaged!&quot; until I enabled it in the bios.&nbsp; I don't have a external port for it) 00:09: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A 00:0a: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A 
ls -la /dev/ttyS* returns this (not really sure what this command is reporting, the last time something was sent to the port maybe??) crw-rw-rw-&nbsp; 1 root dialout 4, 64 Oct&nbsp; 2 22:30 /dev/ttyS0 crw-rw-rw-&nbsp; 1 root dialout 4, 65 May&nbsp; 7&nbsp; 2004 /dev/ttyS1
 crw-rw-rw-&nbsp; 1 root dialout 4, 66 May&nbsp; 7&nbsp; 2004 /dev/ttyS2 crw-rw-rw-&nbsp; 1 root dialout 4, 67 May&nbsp; 7&nbsp; 2004 /dev/ttyS3 crw-rw-rw-&nbsp; 1 root dialout 4, 68 May&nbsp; 7&nbsp; 2004 /dev/ttyS4 From what I can tell the OS sees the serial port fine and communicates with it, however when I attempt to run the script I get this
