Thanks to AD1C/K1EA for the list of CT command-line switches. A few comments, from my personal experience: -K1XM : This switch works fine on my 486, where I don't have a CPU speed problem. It causes my 8088 to crash - that's where I really need this switch to work ! -LOOP : I haven't heard of anyone actually getting this one to work. Steve London, N2IC/0 n2ic@longs.att.com
