DOS ain't dead

Hi all,

Now i've try to run it on win 7 32 bit with ntdvme .
The dos program by default send and read data from radio via com 2 port
Bits Per Second: 9600
Data Bits: 8
Parity: NONE
Stop Bits: 1
Flow Control: Xon/Xoff
I've setted under windows this data on usb port calling com2 .
When i try to read data under windows i receive a message regarding impossibity for the system to open com port2.
I've make same test under dosemu, and the problem remain the same..

The product allows use of external devices such as Parallel (LPT) and USB protection dongles and Serial (COM) port devices.

Hm, WinXP NTVDM doesn't have such problem, I still sometime use old TERM95.EXE and it works fine under XP also at 115200. I know TaoDOS long time but don't have full ver.

DOS gives me freedom to unlimited HW access.

SEEM Dosbox megabuild can manage LPT and com ports

Hi all,

PARTIALLY solved!

1st : a problem on hardware .. require a mod in usb interface for emulate older com interface

2nd NTDVE don't work anymore, but dosemu standard version work fine.
I've installed last version and setting all com ports like realport .
The data flow it's correct and the device it's programmed.
Under ntdve continue to appear a message error regarding the inestence of com2.
(why?)
