Thanks everyone for your input and assistance. The solution was a DB9 Female/Female Null Modem adapter.
STARTECH NULL MODEM ADAPTER DB9 FEMALE TO DB9 FEMALE (NM9FF)
After listing the cables I purchased I realized the gender changer was the offending component. I don't know how I selected a gender changer in instead of a null modem adapter, but everything works like a charm now.
Thanks again.

Tim,
in an old post of yours i saw that you had a "Prolific" device, but you indicated that the chipset was incorrect, CH340/CH341. could that be the case with me even though my adapters show up as pl2303 under windows and linux? how can i check for the specific chipset in use? Below is the link to your previous discussion:

"BELKIN F4A091 DB9 Female/Female Gender Changer"
"Cables To Go - 26886 - 13in USB To DB9 Male Serial Adapter"
"Belkin F2N209-06 CGA/EGA Serial Mouse Extension Cable; DB9M/F"
ok, i tried the following:
d12-100 -> USB Adapter -> DB9 F/F GenderChanger -> DB9 M/F serial extension -> Com/Serial Port
-nothing generated in /var/log/messages
d12-100 -> USB Adapter -> DB9 F/F GenderChanger -> Com/Serial Port
-nothing generated in /var/log/messages
d12-100 -> USB Adapter -> DB9 F/F GenderChanger -> USB Adapter -> USB Port
-nothing generated
I also obtained a d12-300 from ebay and got the same results.
I am beginning to suspect the gender changer as being the culprit because if i just plug the USB adapter into a USB port by itself the following is generated in /var/log/messages:
Feb 17 08:11:42 HTPC kernel: usb 1-2: new full speed USB device using ohci_hcd and address 5
Feb 17 08:11:42 HTPC kernel: usb 1-2: configuration #1 chosen from 1 choice
Feb 17 08:11:42 HTPC kernel: pl2303 1-2:1.0: pl2303 converter detected
Feb 17 08:11:42 HTPC kernel: usb 1-2: pl2303 converter now attached to ttyUSB0
Can you are anyone else confirm the specific gender changer they are using, and also if this specific version of the USB adapter (as displayed in the /var/log/messages output) is working for them?
Thanks

ok, so before you connect the cables start watching the message log,with
tail -f /var/log/messages
then plug in the usb/serial adapter? does it show up? if so that part should be working. note what serial device gets created
then plug in the next one and check the same thing and note which device it is
Then you copy the directv.pl to directva.pl and directvb.pl, edit a to match the first serial/usb adapter the way the system sees it. and b to match the second device.
I then made some labels and labeled the directv stbs A and B and the cables that go to them.
next manually run the directva.pl ( instructions are in the file) with a tv connected to the stb and see if you can change channels with it that way. if that works you can go into mythtvsetup and tell it to use the script to change channels.

Thanks for the info but I checked that link before purchasing my cables. If you look at the cables I listed you will see that I purchased the cables to go usb to serial adapter which was the third cable on the recommended list. Specific brands were not mentioned for the db9 gender changer or the db9 serial cable.
