Cu Write Input/output Error
Contents |
while it's not asserting carrier cu disconnect detect. Two solutions: configure your modem to assert tty input output error this even when it hasn't got carrier to another modem, or put the softcar input/output error serial port flag on tty00 in /etc/ttys. Sorry, there's another solution. Use a program that doesn't care about CD. :) Kermit works nicely. - Joel Reicher On Mon, 26 May

another Unix system. Description The cu command is used to call up another system and act as a dial-in terminal. It can also do simple file transfers with no error checking. cu takes

a single argument, besides the options. If the argument is the string "dir" cu will cu line in use make a direct connection to the port. This may only be used by users with write access to the port, as it permits cu command not found reprogramming the modem. Otherwise, if the argument begins with a digit, it is taken to be a phone number to call. Otherwise, it is taken to be the name of a system to call. The -z or --system https://mail-index.netbsd.org/netbsd-help/1997/05/26/0003.html option may be used to name a system beginning with a digit, and the -c or --phone option may be used to name a phone number that does not begin with a digit. cu locates a port to use in the UUCP (Unix-to-Unix copy) configuration files. If a simple system name is given, it will select a port appropriate for that system. The -p, --port, -l, --line, -s and --speed options may be used to http://www.computerhope.com/unix/ucu.htm control the port selection. When a connection is made to the remote system, cu forks into two processes. One reads from the port and writes to the terminal, while the other reads from the terminal and writes to the port. cu provides several commands that may be used during the conversation. The commands all begin with an escape character, initially ~ (tilde). The escape character is only recognized at the beginning of a line. To send an escape character to the remote system at the start of a line, it must be entered twice. All commands are either a single character or a word beginning with % (percent sign). cu syntax cu [ options ] [ system | phone | "dir" Commands cu recognizes the following commands: ~. Terminate the conversation. ~! command Run command in a shell. If command is empty, starts up a shell. ~$ command Run command, sending the standard output to the remote system. ~| command Run command, taking the standard input from the remote system. ~+ command Run command, taking the standard input from the remote system and sending the standard output to the remote system. ~#, ~%break Send a break signal, if possible. ~c directory, ~%cd directory Change the local directory. ~> file Send a file to the remote system. This just dumps the file over the communication line.

Everything has been going fine and I have not made any changes for a while. However, I have just noticed that Webalizer is no longer producing reports properly (they seem garbled) and now I cannot even copy files via FTP or even do a mkdir without getting an error (see below). Code: mkdir testing mkdir: cannot create directory `testing': Input/output error I tried to s
