In case others don't, it's because the SEND command completed, and the
next command is EXIT. Normally you'd want to put IF FAIL after the SEND
command so you could take some kind of error recovery or notification
action.
: but Is the pathname nak local or is that from the remote ?
:
I believe it's local. Zmodem is sending a file, and I think the Zmodem
protocol wants the receiver to send a NAK as a means of telling the sender
it's OK to send the filename. But it's not getting it.
C-Kermit knows nothing about any of this -- it simply runs your sz program
as an external protocol, with its standard i/o redirected to the
communications connection. The most likely explanation is your version of
Zmodem does not use standard i/o for file transfer. In that case, you'll
have to find another version that does.
