We had a lot of trouble understanding your previous post and recommended that you contact the software authors (when we eventually found out which product called minicom you were posting about).
https://www.unix.com/shell-programmin...t-command.html

However, in general if you can type commands at the command line you can usually compose an expect script.


What are you trying to do?

Corona,
i have an error with your script:


giuseppe@giuseppe-K53SV:~/Scrivania$ ./scriptmodem2
stty: /dev/ttyUSB3: impossibile eseguire tutte le operazioni richieste
Response was ''
AT+CGMI

Response was ''
AT
giuseppe@giuseppe-K53SV:~/Scrivania$

I have change
MODEM="/dev/ttyUSB3"
and

for example:

Start Minicom:
Set serial port ttyUSB3
AT+CREG?
if response != OK then do something
...other AT command (open a socket tcp/ip with at comman)
Send a file .txt for example.
exit minicom.

I saw on the network command "expect" but I have not undarstand how to launch minicom and give it commands to set the right port ..

thanks for help
I don't have a modem now (left it in Antarctica believe it or not), so it is hard to test/script this for you, but Corona is certainly right that you would not use minicom.

PPPD comes with 'chat' which is a good way to do the initial parts of opening connection. I would use that. Again, untested:

Code:
exec 3<&1 >"$modem" <"$modem"
stty 115200 clocal ...etc...
if chat -v -s 'AT+CREG OK ATopencmd CONNECT'; then
   echo "error setup modem" >&2
   exit 1
fi
cat file
echo "done" >&3

Corona:

Code:
giuseppe@giuseppe-K53SV:~/Scrivania$   ./scriptmodem2
stty: /dev/ttyUSB3: impossible to perform all tasks required
Response was ''
AT+CGMI

Response was ''
AT
giuseppe@giuseppe-K53SV:~/Scrivania$

I think that stty is setted badly

# echo AT > /dev/ttyUSB3 not work!
chat -V -s '' 'AT+creg?' '' > /dev/ttyUSB3 < /dev/ttyUSB3
sleep 2
chat -V -s '' 'AT' '' > /dev/ttyUSB3 < /dev/ttyUSB3
sleep 2
chat -V -s '' 'AT!PADSETUP=1,2,82.91.28.127,0,9940,0,1' '' > /dev/ttyUSB3 < /dev/ttyUSB3
sleep 2
chat -V -s '' 'AT+CGDCONT=1,"IP","web.omnitel.it"' '' > /dev/ttyUSB3 < /dev/ttyUSB3
