Re: [Uisp-dev] UART in Linux

Hi Margarita,
thanks for reply!

> 1) Why ttyS1? Are you sure it's not ttyS0 ?
I've checked BIOS of Thinkpad 600E - not so much to play with HW.
BIOS COM port test said "Ok".

If I try to use ttyS0 I have an error:
Error: No such device
-> /dev/ttyS0

Yes stk500 and chip are Ok under windows

Same thing with avrdude: 
$ avrdude -t -P /dev/ttyS0 -c stk500 -e -p m16
avrdude: ser_open(): can't open device "/dev/ttyS0": No such device

$ avrdude -t -P /dev/ttyS1 -c stk500 -e -p m16
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_2_ReceiveMessage(): timeout


Br,
Vitali
