Write fault error com1 port

I have windows xp and I am trying to write to Com1: with DOS version
0.82. I am using RXD, TXD, DTR, DSR, RTS, CTS lines in the cable.

The dos commands used are

1) mode com1:2400,n,8,1

Status for device COM1:
-----------------------
Baud: 2400
Parity: None
Data Bits: 8
Stop Bits: 1
Timeout: OFF
XON/XOFF: OFF
CTS handshaking: OFF
DSR handshaking: OFF
DSR sensitivity: OFF
DTR circuit: ON
RTS circuit: ON


2) echo "print" >com1:

This command issues Write fault errors

Error writing to device COM1: write fault
(A)bort, (I)gnore, (R)etry, (F)ail?

How do I solve the problem

Thankyou in advance

try reducing the baud rate to 1200
