The operating modes are assigned the following transmission protocols:
The following applies to all data transmission protocols except LSV2:
If an incoming file is already stored in the iTNC, the TNC will ask you whether
you really wish to overwrite this file:
Press a soft key to continue the transmission.
If you attempt to overwrite a write-protected file, the iTNC displays the
Protected file! error message:
Press the MORE FUNCTIONS soft key and then the UNPROTECT soft key
to cancel write-protection and continue transmission.
If a file has been read out and the data transfer menu has been terminated
with the END key, the iTNC outputs the characters <EXT> and <EOT>.
If a transmission is terminated with the END key, the error message Program
incomplete is issued.
