How to access console port on pan-2020 using a dial up modem

So here's an idea... do you have a spare router lying around that has an aux port that you could test on? At least you could see if your cable and modem serial port are good and working...

I can console into the modem to issue the at commands using my pc's serial port, so that would suggest the serial port on the modem is working right?  I can also console in successfully to the firewall from my pc's serial port which tells me the rollover cable and connections are good as well right?

The modem comes with a 2 headed cable, one with an rs232 connector and the other a db9.  I have tried using an rs232 gender changer to connect the modem to the console port of the firewall and that didn't work, I also did the same thing with a db9 gender changer to connect the db9 connector to the console port as well and still no success.  I have turned off compression as well with no success.  I know my modem is connecting to the firewall modem because it says "connected 9600" but won't respond to anything after that.  I can issue the +++ command to break out of it and that's it.  I may just have to break down and purchase a serial console server unless you guys have any other ideas?

I'd love to help figure this out (I like the challenge...) but I don't have an old school modem and POTS line to try connecting to a lab PA unfortunately.

It "feels" like a pinout thing... like the modem's pinout and the PA's pinout aren't 'lining up right' for whatever reason, but it's really hard to narrow down why
