I can not get this modem setup correctly on a Cisco router.

Use hyperterm and configure the modem with these commands:

First ensure your terminal is set to 9600bps and the modem is getting a TR light.

Here are the commands with responses:

AT&F&Y&W<cr>OK
AT&W1Z<cr>OK
ATI1I2I3<cr>255 ACF3_V1.702A-V90_P21_FSH<cr>OK
AT+IPR=9600<cr>OK
AT+MS=V34,0,9600,9600,9600,9600<cr>OK
AT&D0&K0Q1E0&W<cr>

Note the last AT command string (AT&D0&K0Q1E0&W) will not return an "OK" as echo and results are turned off.
