I’m working on a virtual COM port driver.
I started from WDK 8.1 VirtualSerial example a little update to made a simple echo driver.
I got problems when I try to connect with Tera Term terminal on create Virtual COM port.
What I see is that on open, Tera Term stay waiting on IOCTL_SERIAL_WAIT_ON_MASK.
I don’t understand what is the problem, because some others terminal (hercules for example) are working.
Debugging in driver give me no error code.
This is the log I see with a serial monitor:
13 0.00002470 ttermpro.exe IOCTL_SERIAL _SET_CHAR 00000037 SUCCESS EOF:0 ERR:0 BRK:0 EVT:0 XON:0 XOFF:0
