Hi,
When I connect my MC7304 to my linux computer I see three new serial ports created:
/dev/ttyUSB0
/dev/ttyUSB1
/dev/ttyUSB2
I’m able to send AT commands and start a PPP session using /dev/ttyUSB2 using settings: 115200 8N1 + Hardware Flow Control.
What are the other ports for?
If they are usable can I use them to send AT commands to the modem while the PPP session is established?
Thanks

What are the return of the following?
At!entercnd=“A710”
At!udusbcomp=?
At!udusbcomp?
You might need to use cmux if AT port is used for ppp
At!entercnd=“A710”
ERROR
At!udusbcomp=?
ERROR
At!udusbcomp?
