Serial Port with Dos Applicaton

[Leira2412]

Hello sir i would like to know if otvdm is compatible with 16 bits msdos Console Application that use serial port with Interrupt 14 ? OS is Windows 10 x64 1909

the equipement send data through serial port (COM1) and when we use serial port monitoring we see that data comes but when run msdos Application nothing happens, i also look if anything what happening on serial port, like opening serial from otvdm, but it very silent.

If interrupt 14 is supported with otvdm , how can i catch the trace with msdos application, i tried to put WINDEBUG environment variable and run otvdm --appname app.exe and redirect it to a log file but it just mess up the console with many messages and nothing is going to the log file. Thank you
