Dos command Print strange behavior

[Vin]

Hi,

I have a document that I want to print using the Dos command Print.

- I am using a laptop with XP Professional installed
- My printer is connected to the serial port (com1 with settings of
baud=115200, DataBits=1, Parity=none, Stop bits=1, Flow control is Xon/Xoff

When I send it either a text file about 3kb in size using either:

Print /D: COM1: file.txt
Copy file.txt COM1:

The printer will start to print, but then it stops and then start printing
garbage. But when I reset the baud to 9600, it will print just fine.

Anyone knows what's going on here? Is Dos print command only using baud of
9600?

How can I using the COM1 port with 115200 baud rate?

I have also tried MODE LPT1:=COM1: and print through LPT1:, but I still have
the same issue.

Any Ideas?

Thanks!

9600 is standard. The printer probably can't handle 115200.

The printer can handle 115200 because it is working before until Windows XP.

Then just use what works. Nuff said...

Ah, okay. Well, use 9600 then.

9600bps is way faster than the computer can print anyway, so nothing is
lost.

Maybe the motherboard drivers you used for Windows XP are not the
correct ones?
