I want the perfect user-interface

I've got an aix-box somewhere on the network and a PC on my desk. Nothing fancy so far.
The PC is made dual-boot:
- windowsXP with putty & winSCP
or
- slackware 13 with xfce4 installed.

The aix-box runs DB2 v8.2 and I've installed db2top to monitor the database.
db2top is a character based app (like top) and can display a lot of usefull information in a nice way.

So I try to figure out how I can present this info on my screen
1) linux character based (tty1, tty2, etc): Just ssh to aix and start you app. Does not work because aix is not aquinted with "TERM=linux". So you overrule this by typing "export TERM=dtterm" and all is good: nice colors and nice line-draws.
When you start GNU-screen first and then ssh to aix, you font is suddenly not able anymore to display lines. Strange...
2) linux grahical: on your xfce desktop you start Terminal (the standard xfce4 term app) and ssh to aix.
Now you do not get your colors (TERM=xterm) so you try TERM=dtterm. Now you do not get your lines drawn (same as GNU-screen mentioned earlier)
The next option is "TERM=aixterm" That looks better:
Colors? Yes!
Lines? Yes!
Perfect? No! The lines are not aligned.... A screen-row with a line starting on a position > 1 is aligned right.
Windows+putty give the same results as xfce-terminal: not perfect.

I thought that installing linux on my desktop would give me a perfect user-interface to my aix-boxes.
Was I too optimistic?

BOOTCTL(1)                                                            bootctl                                                           BOOTCTL(1)

NAME
bootctl - Control the firmware and boot manager settings SYNOPSIS
bootctl [OPTIONS...] status bootctl [OPTIONS...] list bootctl [OPTIONS...] update bootctl [OPTIONS...] install bootctl [OPTIONS...] remove DESCRIPTION
bootctl checks, updates, installs or removes the boot loader from the current system. bootctl status checks and prints the currently installed versions of the boot loader binaries and all current EFI boot variables. bootctl list displays all configured boot loader entries. bootctl update updates all installed versions of systemd-boot, if the current version is newer than the version installed in the EFI system partition. This also includes the EFI default/fallback loader at /EFI/BOOT/BOOT*.EFI. A systemd-boot entry in the EFI boot variables is created if there is no current entry. The created entry will be added to the end of the boot order list. bootctl install installs systemd-boot into the EFI system partition. A copy of systemd-boot will be stored as the EFI default/fallback loader at /EFI/BOOT/BOOT*.EFI. A systemd-boot entry in the EFI boot variables is created and added to the top of the boot order list. bootctl remove removes all installed versions of systemd-boot from the EFI system partition, and removes systemd-boot from the EFI boot variables. If no command is passed, status is implied. OPTIONS
The following options are understood: -h, --help Print a short help text and exit. --version Print a short version string and exit. --path= Path to the EFI System Partition (ESP). If not specified, /efi, /boot, and /boot/efi are checked in turn. It is recommended to mount the ESP to /boot, if possible. -p, --print-path This option modifies the behaviour of status. Just print the path to the EFI System Partition (ESP) to standard output and exit. --no-variables Do not touch the EFI boot variables. EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise. SEE ALSO
