Problem reading from COM1
Hello,
I have installed Cygwin on a windows98 computer.
I have a problem using the serial port. (COM1)
It is possible to write to COM1 but impossible to read from.
ls >com1
data is send and received
cat< com1
nothing is received.
I did several tests with different programs.
But nothing is received. (under cygwin)
A normal HyperTerminal on windows did work.
The stty command have the following settings.
$ stty -F /dev/com1
speed 9600 baud; line = 0;
intr = <undef>; quit = <undef>; erase = <undef>; kill = <undef>; eof =
<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
$ stty -F /dev/com1 cread
stty: /dev/com1: unable to perform all requested operations
Why CanÂt I read from the COM1?
Is it because I use windows 98?
Why canÂt stty set cread?
Thanks Robert Bon
