I have a TP720 (ok, I know it is notthe 720 list, but there is > no 720 list! this will probably apply anyway) Maybe, maybe not. The 720 is a wierd bird. For example, it's a micro-channel machine (not ISA) and so there are a bunch of d*mn POS registers (love that name) that govern whether the devices (including the PCMCIA controller) appear on the system bus. My TP720 tech ref manual says that the enable bit in the POS register for PCMCIA is zero on power up, meaning that the PCMCIA subsystem is *disabled* by default. > and a Megahertz modem.

If so, then it is indeed a TP720 specific problem. In addition to the POS registers, the PCMCIA subsystem also requires its own initialization, say, to map a modem card into the i/o bus as a COM2 port. Again, you might have a Windows driver that will do this for you, whereas it wouldn't happen under DOS alone. Depending on what PCMCIA controller chip the TP720 uses (the tech ref manual is silent on the subject) this problem might or might not be specific to the TP720. @end(theory) Disclaimer: I don't have a TP720 any more, so I don't really know much about them.
