Thanks a lot for the information, I'm a newer user of SCO Unix but i will try to do the maximum to resolve this with a help of you... the script I got to do it only contains the lines you write ......
Well... finally I took and old SCO Server and it works fine to keep working my ERP, but now I have a "LITTLE" trouble... with the other server we've made a connection trought TinyTerm with a DYNDNS...
