A ha, you're the same guy whose post I answered in comp.dcom.modems a few minutes ago.
So piecing your story together, I have gathered that:
- you have USR Courier modems
- you have (some model of) Cisco routers
- the Couriers are cabled to the router console ports at some (unspecified) speed
So ... I will add some observations that may or may not be helpful here ...
a) If you have a Cisco 8xx router with the console/aux port, then we definitely have seen problems communicating w/ Courier above 57600 bps. (Although I'm not sure that we tried with 2 stopbits.) So, try 1 stopbit, try slower speeds.
b) It's somewhat tricky to configure a modem on a console port - see below for my deep wisdom on the subject that I try to impart to the Cisco TAC ...
Good luck,
Aaron
