Some equipment uses 'TTL' levels (0=0.3V and 1=4.7V) but
uses the same signal protocol. In most standard PC serial
connections that's not standard, but watch out for it all
the same. Interfacing the two standards is cheap, can be
done with few parts, but damage can result otherwise, to
the TTL side.

Normally as Paul said, no problem. Serial is one of the
most reliable metal-wired standards, which is why it
refuses to die in heavy industry.

In case you're not familiar... for binary file handling,
try to get software that can handle Z-modem transfers.
There are also X- and Y-modem standards, but Z-modem is by
far the least awkward. I think it can also queue files so
you don't have to nursemaid what can otherwise be a
horribly tedious business.

Thanks, I appreciate the extra info.



You're welcome. Anyone willing to respect a thing when it's good, not just
denigrate it because it's 'old' is doing good things as far as I'm concerned.
