ublox SARA-U260 not showing up in mmcli

[Schroer, Jens Peter]

Just for comparison the output for the ACM0 port on my systems:
speed 57600 baud; rows 0; columns 0; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^A; eol = <undef>; 
eol2 = <undef>;
swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = 
^W; lnext = ^V;
discard = ^O; min = 1; time = 0;

Given your output your modem is configured to run with 9600 baud on 
ACM0.
If you use minicom and set it to 9600 baud what happens?
