Hi,

I need to use a piece of dos based software and hardware via serial port that only works on PCs slower than 233mhz.

I have dual boot Win XP and Dos 7.1

The PC can see the hardware from DOS 7.1 but not via Windows XP.
I have tried DOS Box from Win XP but the software couldn't see the hardware.

Is there a version of DOS Box that will run on Dos 7.1 ?

Many Thanks
Lou

Edit dosbox.conf and look for some statements resembling something like this:

[directserial] # directserial -- Enable serial passthrough support. # comport -- COM Port inside DOSBox. # realport -- COM Port […]

[directserial]
# directserial -- Enable serial passthrough support.
# comport -- COM Port inside DOSBox.
# realport -- COM Port on the Host.
# defaultbps -- Default BPS.
# parity -- Parity of the packets. This can be N, E or O.
# bytesize -- Size of each packet. This can be 5 or 8.
# stopbit -- The number of stopbits. This can be 1 or 2.

I think you need to enable it and give it proper values.

Hi,

Just tried that. checked win xp com port 1 settings and put in

directserial=true
comport=1
realport=COM2
defaultbps=9600
parity=N
bytesize=8
stopbit=1

But the software in DOSbox still couldn't see the hardware on my com port?

Thanks
Lou

Tried both com 1 and 2 just incase....

directserial=true
comport=1
realport=COM2
defaultbps=9600
parity=N
bytesize=8
stopbit=1

directserial=true
comport=1
realport=COM1
defaultbps=9600
parity=N
bytesize=8

Both didn't fix it
