Very interesting. NCurses is OK, but if you can directly use escape codes you are way ahead. That depends on what escape codes your terminal uses. The Linux terminal emulator escape codes described in the console_codes man page are mostly based on the VT100 terminal. NCurses uses the terminfo database to map C library functions to escape codes from your TERM environment variable. I am also very interested in embedded appliances and serial port termios interfacing. Most microcontrollers have a UART like interface and can do real time work. I've done some FreePascal work and posted a demo and Linux console code unit there. But TCL shell control is ideal. Variables can be played with on the fly. Thanks for the post. RE

The tput command should be available on any UNIX or UNIX-like system, and allows you a measure of abstraction away from using direct escape sequences for terminal control. See 'man tput' and 'man 4 terminfo' (depending on what kind of UNIX you have, that might need to be 'man -s 4 terminfo') for more information. Also see, for example, http://tldp.org/HOWTO/Bash-Prompt-HOWTO/x405.html and http://www.ibm.com/developerworks/aix/library/au-learningtput/index.html -Edelson -- It used to be said that AIX looks like one space alien discovered Unix, and described it to another different space alien who then implemented AIX. But their universal translators were broken and they'd had to gesture a lot. -- Paul Tomblin |
