Well my W2k system shows rates down to 75 baud, and includes 110, 134, 150 before getting to 300. I suspect your only problem will be on a non-PC based system, but suspect that any system will have the basic divider hardware in there anyway, so doubt it will be a problem. -- http://www.piclist.com hint: The PICList is archived three different ways.
