Serial port (com)

Serial port (com) What name is specified in dev?
what is tq2440_serial0?

In linux, if you use mini2440 serial ports, they are named ttySAC0, ttySAC1
and ttySAC2, you can see them if you access /dev/ folder.

Ok
I see /dev/ttySAC0 and try to canect it by python but see this Error 00000
then try by Converter com to usb and use /dev/ttyUSB0 my cod work very good
!
Kernel could be a problem?

Hi lamp

the factory default kernel dosn't support usb to serial devices. You must
compile your own kernel, this feature enabled. 
make menuconfig 
Device Drivers --> [*] usb support --> [*] USB Serial converter support -->
<device>
Which <device> to check, this I tried out on my host system. Plugging in
the device, after them a dmesg call shows you the used driver.
