Back in the mid-90's I kept a Poqet PC in my bag or desk to use as
an ad hoc console terminal for data center gear. Wasn't as convenient
as the then current HP palmtops, but a heck of a lot cheaper and an
easier keyboard if the HPs were a tad small for you. MS-DOS in ROM
supported Kermit nicely for ANSI terminal emulation.
California Digital (not the newbies that bought VA Linux' hardware
operation) still has them, though perhaps a bit (ahem) overpriced:
