Hello everyone, I'm using cygwin 1.7.2 on Windows 7, and I am unable to set the icrnl flag for /dev/ttyS2 as shown at the bottom of my message. The device attached to ttyS2 is a ARM development board which uses an ftdi chip for serial communication over USB. (The device is connected with USB, and the driver creates a virtual com port.)
I use driver version 2.06.02 from http://www.ftdichip.com/Drivers/VCP.htm (a bit more elaborate:) I show the problem using stty, but I actually encountered it when testing a serial communications program I've written for linux originally. When compiled under cygwin, it behaves differently. After adding some debug info, it shows indeed that the program recieves an ascii 10 (new line) under linux, where under cygwin it recieves an ascii 13 (carriage return). How to produce: (commands & output pasted chronologically) i...@turtle ~ $ stty -F /dev/ttyS2 speed 9600 baud; line = 0; intr = <undef>; quit = <undef>; erase = <undef>; kill = <undef>; eof = <undef>; swtch = <undef>; susp = <undef>; rprnt = <undef>; werase = <undef>; lnext = <undef>; flush = <undef>; min = 0; time = 0; -cread -brkint -icrnl -imaxbel -opost -onlcr -isig -icanon -iexten -echo -echoe -echok -echoctl -echoke i...@turtle ~ $ stty -F /dev/ttyS2 icrnl stty: /dev/ttyS2: unable to perform all requested operations i...@turtle ~ $ stty -F /dev/ttyS2 speed 9600 baud; line = 0; intr = <undef>; quit = <undef>; erase = <undef>; kill = <undef>; eof = <undef>; swtch = <undef>; susp = <undef>; rprnt = <undef>; werase = <undef>; lnext = <undef>; flush = <undef>; min = 0; time = 0; -cread -brkint -icrnl -imaxbel -opost -onlcr -isig -icanon -iexten -echo -echoe -echok -echoctl -echoke
