Does anyone have the proper USR Sportster V.92 Config wih Cisco Router for OOB on an AUX Port?

I have connected Sportster modems to Cisco routers in the past and had good success.  I saw detailed config suggestions from lrmoore and others for the old 33.6 models as answers to previous questions.  I have change DIP switch settings and tried some AT commands on the modem.  I have also tried customizing the Stopbits and other modem specific features on the AUX port.  I am trying to dial in from Hyperterminal under Windows XP.  When I first set this up I could connect to the modem but never got a Login to the Router.  After making more changes I have had difficults even get past the handshake and get a connection.

Please see part of my working config (Cisco 2520 router and USR Sportster 56K modem)

interface Async4
 description dialup
 ip unnumbered Ethernet0
 encapsulation ppp
 async mode interactive
 peer default ip address pool default
 ppp authentication pap ras
line aux 0
 modem InOut
 modem autoconfigure discovery
 transport preferred none
 transport input all
 autoselect during-login
 autoselect ppp
 speed 38400
Also, you should set your modem for autoanswer (via reverse-telnet to the modem)

Your config was very helpful.  But, I am still having a problem even though it is much more isolated.  Whenever I reboot the router the speed setting changes from 38400 (even though this is specified in the Startup) to 115200.  If I try dialing in I get garble.  If I go in via telnet or the console port and change line aux 0 to speed 38400 then I am able to connect every time and am able to read the screen.  If there are way to force the router to keep the speed 38400 after it boots up?  Any other suggestions?
Check your modem configuration - "modem autoconfigure discovery" tooks modem settings and thats probably why you having 115200 after every reboot.

Reverse telnet to your modem and see its configuration with ATI4 command.

Look here for AT commands: http://www.helpdesk.umd.edu/topics/communication/dialup/hardware/2153/

If you having problems with reverse telnet - connect your modem to the PC's com port and start HyperTerminal.

Thanks for the update.  I have limited experience with these settings but do not see anything related to 115200.  I have included a dump of the ATI4 command below and a dump of the show line aux 0 after reboot.  However, I did notice that even though I specify 38400 in the startup-config, when the router re-boots both with AND without the modem attached the speed on the aux port is changed to 115200.
