Description: |
This patch refers to ID: 2413550 -------------------------------------------- The following patch performes a "name hint" to detect native Windows serial port name by one of the following patterns (case-insensitive). Pattern matching is checked quite restrictive, because *all open-filenames* need to pass this test. COM[1-9]:? \\.\COM[0-9]+ //./COM[0-9]+ For all filenames not matching the patterns above, the original behavior open-close-reopen is preserved, thus supporting (virtual) comports of any other name: 1. Open channel with NON-OVERLAPPED flag 2. Detect serial port by checking GetCommState() result 3. Reopen the serial port with OVERLAPPED flag This behavior can be enforced even for native Windows serial ports e.g. with [open /com1 r+] | |||
