Hi,
I need a way to detect the up and down arrow key inputs for my program. I do not want to wait for the return key to be entered(so that rules out getch() and family). Also I need to process several of these inputs in parallel, by servicing each request with a thread.
Is that possible?

rcmd
RCMD(1) BSD General Commands Manual RCMD(1)NAME
rcmd -- backend driver for rcmd(3)SYNOPSIS
rcmd [-46dn] [-l username] [-p port] [-u localusername] host command
DESCRIPTION
rcmd executes command on host.
rcmd copies its standard input to the remote command, the standard output of the remote command to its standard output, and the standard
error of the remote command to its standard error. Interrupt, quit and terminate signals are propagated to the remote command; rcmd normally
terminates when the remote command does. The options are as follows:
-4 Use IPv4 addresses only.
-6 Use IPv6 addresses only.
-d The -d option turns on socket debugging (using setsockopt(2)) on the TCP sockets used for communication with the remote host.
-l By default, the remote username is the same as the local username. The -l option allows the remote name to be specified. Another pos-
sible way to specify the remote username is the notation user@host.
-n The -n option redirects input from the special device /dev/null (see the BUGS section of this manual page).
-p port
Uses the given port instead of the one assigned to the service ``shell''. May be given either as symbolic name or as number.
-u The -u option allows the local username to be specified. Only the superuser is allowed to use this option.
Shell metacharacters which are not quoted are interpreted on local machine, while quoted metacharacters are interpreted on the remote
machine. For example, the command
rcmd otherhost cat remotefile >> localfile
appends the remote file remotefile to the local file localfile, while
rcmd otherhost cat remotefile ">>" other_remotefile
appends remotefile to other_remotefile.
FILES
/etc/hosts
SEE ALSO rsh(1), rcmd(3), environ(7)HISTORY
The rcmd command appeared in NetBSD 1.3 and is primarily derived from rsh(1). Its purpose was to create a backend driver for rcmd(3) that
would allow the users of rcmd(3) to no longer require super-user privileges.
BUGS
If you are using csh(1) and put a rcmd in the background without redirecting its input away from the terminal, it will block even if no reads
are posted by the remote command. If no input is desired you should redirect the input of rcmd to /dev/null using the -n option.
You cannot use rcmd to run an interactive command (like rogue(6) or vi(1)). Use rlogin(1) instead.
The stop signal, SIGSTOP, will stop the local rcmd process only. This is arguably wrong, but currently hard to fix for reasons too compli-
cated to explain here.
