The WIKI is, of course, correct in this instance. I had forgotten that the -G
means "good connection" or some such and that it does no error checking. Is
there a fall-back to Y-Modem available? Heck, even X-Modem as you are probably
on Tel-net and not paying overseas LD phone rates.

You'd probably be fine in my Springfield. Especially as they have been
rebuilding the infrastructure. Sadly, not upgrading to fibre optics as they go.
And according to the AT&T field-techie working behind my house - the only
places in this area likely to get fibre are the new, upscale sub-divisions.

As to your chances in Casper ... it will depend on Wendy (Harvey comix
reference).
