Anyone copying files from Unix to AS400?

We have a new Intel server where the application runs KornShell under MKS 
Toolkit on Win2k Server.  We create files that need to go to the AS400 and 
under the old DOS Based version of the system, I just use a DOS COPY to the IFS 
and then execute this command to get the data to the native AS400 file system:

RMTCMD CPYFRMIMPF FROMSTMF('qdls\OPERATNS\EXTMNTCF.CSV') 
TOFILE(SFNBACH/SLCIFNEW) RCDDLM(*CRLF) MBROPT(*REPLACE)

I replaced the DOS COPY with:

cp ${CHARTER_FILES}/EXTMNTCF.CSV \\S103080D\QDLS\OPERATNS\EXTMNTCF.CSV

These commands seem to fail.  Anyone with experience in these system know if 
the CP command supports the UNC File syntax and how do you format the RMTCMD so 
as not to get a syntax error from the parenthesis in the command parms?  Quotes?

Thanks,
