echo '\007' send the bell character: so you can send the character you want (ASCII coded), using \ and 3 octal digits

echo '\0101' will echo the "A" character

octal digits used in shell always begin with \0

you must know the characters you want to send: combinations of alt & ctrl genarate ASCII characters

CompTIA Network+

Prepare for the CompTIA Network+ exam by learning how to troubleshoot, configure, and manage both wired and wireless networks.

1° scancodes are generated by the keyboard, then interpreted by the software of your modem, traducing scan codes received in ascii codes , sending them to the modem.
2° ALT/CTRL/SH ... are not traduced by the system;
you must found ascii sequences to tend to your modem : check the documentation of it, or connect on the server of trader, or if unsuccessfull, during using modem thru normal software: pick up sended characters with a terminal connected in electrical parallel on COM
3° finally, if this is not successfull, your question become
" what are the ascii sequences to send commands at the dialer"

I suppose commands are HAYE compatibles: you can try to send some HAYE commands to verify compatibility.

I think the ALT+c is sent by localy, to may dialer.
There is no need for it to be sent via modem to the server, since the server has started allready the ppp connection.

All I need to do is tell may dialer to start using the ppp localy too, that is done by Pressing ALT+c.
If i want to emulate this key in script i would need to know its esc seq,
I am quit sure this is a common quastion since this is the case for any kppp dialer user, who tries connecting to his Internet Provider by script.
