I am suspect it is running cexp, it says to type that but typing that gives
me a cexp error, though typing help() works and gives this for a help
command, which seems to be missing the mount method :(
(also Peter Dufault recommended using ikup("mount") but that yielded no
command either). cexpr() failed as a command too. The login showed:
telnet 10.50.1.111
Trying 10.50.1.111...
Connected to 10.50.1.111.
Escape character is '^]'.
Password:
[Telnet:] starting cexp on /dev/pty0
Type 'cexp.help()' for help (no quotes)
cexp.help() though is a lie, but help() produces the following:
(Somewhere the source code has to be abound but not sure where, we got no
documentation from outgoing IT).
alt-rotator>help()
Module commands:
mod = ld("filename") - load filename object and return handle for unld()
lsmod() - list loaded modules and their handle
unld(mod) - unload inactive module by its handle
Files and directories:
cat(filename) - copy file to screen
cd(path)
copy(filename,filename) - usually used to install files from /rtems to
/apo
ls()
home() - change directory to $HOME. Right now /apo
mkdir(path)
new_rtems()
pwd()
rm(filename)
