modem dial-in to Cisco 2600 problem

And

4) when first password timeout expires to tell router to give one more prompt. And if password timeout expires again, another prompt (last one)?

line aux 0 exec-timeout 15 0 login local modem InOut modem autoconfigure discovery transport input all stopbits 1 speed 115200 flowcontrol hardware

1) When I connect why do I get this (red letters):

CONNECT 31200/ARQ/V34/LAPM/V42BIS

% Login invalid

Username: 0 V42bis Password:

2) how can I set that after 3 unsuccessful login attempts, user gets disconnected? 3) Why every time I connect to my USR external modem over Hyper Terminal I have to enter atz command to see what I write?

Thanks! I appreciate :)
