Thank you very much for your reply . According to your message , the minicom is not suitable in this regard as I really want remote desktop access to my CentOS client located at far site and thus get its keyboard & mouse control to issue commands and view Gui . Please do me favor and propose for the solutions that can enable my CentOS server at the office to get remote desktop access of my CentOS client far at the site (the only connections that can be made is through modem dialup connections) .
GUI over a 28k dialup? ouch. there's no network connection at this remote site? its going to be really really slow over dialup. I'm talking minutes to paint a screen at 2-3kbyte/sec serial speeds (a 1280x1024 24bit desktop is 3.6 million bytes). use a really simple theme on the desktop with no shaded borders, no backgroun graphics ('wallpaper'), etc. Sending a single full screen 1280x1024 photographic image could take a half hour or more.
FreeNX is probably your best bet. i've never set it up, so you'll need to find someone elses HOWTO ... NX protocol runs over TCP/IP networking, so you'll be setting up your modem (I still recommend a serial modem) to answer a PPP dialinn TCP session, which you'll connect to with a PPP dialup session much as we did for the internet in the days before broadband.
linux can be completely managed via shell. NONE of the dozens of unix servers I manage have any sort of console screen attached to them.
