Certainly, Xmodem would be faster than the most generic Kermit since it
uses an 8-bit data path as opposed to the 7-bit path of Kermit. I
usually think of Kermit first when transferring files because there are
so many different implementations. Just about any operating system has
one or more versions of Kermit. Even the HP calculators have Kermit
(the 48 and 49 I think).

Also, unless you have the Ymodem variant or later, I believe you have to
type in file names to the receiving end. Kermit usually can transfer
the file name as part of the transfer.

I have several programs that can use Xmodem, Xmodem-CRC, Ymodem,
Ymodem-1K on Intel MDS systems. Probably can also find some of those
for the PeeCee.

However, I just always think of Kermit first because I don't even have
to think of what operating system or what kind of computer. Kermit will
be available.

That being said, I DO agree with you that it would seem much more
"appropriate" to be using one of Ward's protocols to transfer his files.
