serial port via minicom: can minicom use line-editing (i.e. readline functionality)?

I am successfully talking to a board connected over a serial port interface to my PC. I can both send and receive bytes - but for interactive applications executing on the board, that try to read inputs from their stdin, minicom doesn't seem to offer any kind of readline-like editing functionality:
// code running on the embedded board
printf("Reading a number: ")
scanf("%d", &i);
In minicom:
$ minicom -D /dev/ttyS0 -b 38400
...
Reading a number: 1a^H
Once I enter an 'a', I can't backspace over it.
Note there's no shell or anything in between here - this is plain minicom over a serial line, nothing more.
screen /dev/ttyS0 38400 seems to work fine - allowing me to edit the line and only sending it to the serial when I press ENTER.
Can minicom be configured to do the same?

screendoes its own line buffering,minicomdoesn't. If the application on your board you're talking to doesn't offer that kind of line editing, you're out of luck.

Consider using rlwrap to add readline's advanced line editing features to any simple terminal program. I'm not sure if minicom would work fine with it since it features quite a complex UI; if not, try picocom.
