error in (read) ing comma inside backquote

[graham@vax2.cstp.umkc.edu]

I get an error whenever I try to use (read) to input a backquoted expression
containing ",x"  (",@x" works OK)   from *terminal-io*.  It happens when the
system reads the "x", realizes it isn't an "@" and tries to (untyi) it.  Is 
there a solution or work-around? 

thanks,
