Procomm Plus will not keep up with a full duplex ascii transfer at 19.2 Kbps. A full duplex ascii transfer is _the_ comm program torture test. The best I've found (in spite of its user interface which I hate!) is Hayes Smartcom III. It will handle 19.2 Kbps full duplex ascii transfers on two serial ports simultaneously. This is a good thing when you're using PCs and comm programs as lab test equipment. (I remember once spending hours looking for a bug in a serial driver because a PC comm program was dropping characters. Now I get a protocol analyzer FIRST :-) // marc -- // work: marc@ascend.com uunet!aria!marc // home: marc@dumbcat.sf.ca.us pacbell!dumbcat!marc
