I seem to recall having a problem with some modem software taking over my external serial port on a 540C. You might try disabling the modem extensions and see if that fixes the problem. You might also try using a program called "Terminal." It's freeware, and you can find it with a search for terminal-22.hqx . I use it a few times a year- my powerbook is *much* lighter than a vt-100! -- Dana mac at ozymandias.unm.edu
