When I type in commands at the command prompt and hit enter, some of the
commands are getting run twice.
For instance, version gets run twice while an md runs only once.
=> version

One thing to note about my setup is that I am accessing the serial
console using telnet over a remote serial devices server. So the whole
telnet end-of-line issue and the processing of CR,LF, and NUL come into
play.
Snooping the network and watching the character counts on the seriver
server's serial port, I can see that each time I hit <Enter> there are
two characters going over the serial line (CR-LF or CR-NUL) to the
target.
My questions are:
1) Has anybody else encountered this problem? I already googled for an
answer but came up with nothing.
2) Does anybody have any idea why some commands are working and others
are not? I would expect that either all would be repeated or none of
them would be repeated.
Thanks,
Jeff
