Specify COM port file in java -

-

in unix operating systems, can access serial ports through files such /dev/ttyusb0 or something. , according question, filenames such com1: can used access serial ports. java alternative such file names? don't want use serial communication liberaries.

edit

what want code this.

string input_port_file_name = linux?"/dev/ttyusb0":"<file name of comport>"  file in = new file(input_port_file_name)

what want widows alternative device file.

edit on linux machine, , want enable code ported easily!

yes, on linux there access serial port instance through device files /dev/ttys0, /dev/ttyusb0 , others. depends on hardware/chips used communicate , distributions.

if same hardware used in program can partly achieved. when worked serial comm libraries , real physical serial ports in linux used port numbers in config number 3 meant n=3, opens "com"+(1+n) on windows or "/dev/ttys"+n on linux. maybe similar can used accessing port on /dev/ttyusb"+n

but there no grantee port 2 /dev/ttys1 , com2 on same computer after dual boot.

the way not using serial comm libraries hard way , not recommend if want portability in java. recommend different port config depending on operating system.
