Serial port and Qtextedit or Qtlinedit

[eva2002]

Hi all,

I am currently working on a project on an arm9 board with touchscreen (w/o keyboard attracted). However, I need to communicate the board with 'minicom' hyperterminal running on my laptop via serial cable.

What I need is whenever I press a button on my laptop, will be reflected on the Qtextedit or Qtlinedit widget. How can I proceed in doing this?

I was hoping to just use linux serial communication files ie termios to aid with the serial communication instead of Qextserial. (as my ram is very limited).

I am using qt-embedded-linux-opensource-src-4.5.2.

Thanks.

Regards,
Stanley
