There are modem-specific commands that tell the modem to do what
the telephone would do if you pressed dialing keys. ATDT123 tells the
modem to send the DTMF tones that correspond to Touch-Tone telephone
1, 2, and 3 keys.
The modem can't read keystrokes from the PC keyboard. It's the other way
around: the PC software (Kermit in this case) sends data (keystrokes,
scripted, or otherwise) to the modem. When the modem is in command mode,
you have to send it legal AT commands.

:
"Wait for bong" usually refers to credit card tones. This might not be
what you have to wait for in your case. The real question is whether the
modem provides sufficient information to the computer, or has its own
commands, that will allow you to automate a process that relies on audible
tones.
