Subject: Problem redirecting to COM1 in DOS 3.3

I just received the following message when trying to redirect
output to COM1 (which is connected via null-modem to a Sun
workstation):

  c:\>  echo logon > com1  [enter]

	Write fault error writing device COM1
	Abort, Retry, Ignore, Fail? 

I'm using DOS 3.3 on a highly IBM compatible clone.  It doesn't 
complain when I issue the same command to COM2, (an internal 
modem not connected to anything at the time).  I tried rebooting
but that didn't help...also tried setting the port with MODE but
no luck either.  The DOS manual doesn't list this error message.
I've this before on an IBM PC/AT with no problems at all, using
COM2 (without using the MODE command).

The line is configured (on the Sun, anyway) at 9600 baud, and it
works great when using Crosstalk or Kermit 2.3.  

Any help appreciated,

Doug
