Telnet Emulation Connected but Screen Blank

i got this when installed V4R4 Licensed Program ...

All the necessary Licensed Program, with no error msg about licensed program installation in log file. However, i chk back & found that during licensed program installation stage, the option s for Client Access Family : 5769XW1 *BASE & *Option 1, didn't actually exist
for selection at all. So i restored both of these options, *BASE followed by *Option 1, from installation CD to system, but for *Option 1, it says '... *Option 1 not restored ...'.

When testing iSeries client access from a Windows pc to server :

-Connection status of telnet emulation was successful, but
-the emulation screen was blank


i tested from another Windows client pc but got the same problem. So i restored again 5769XW1 *Option 1, this time restored ok. Retest iSeries client access & the problem went away.

i find this quite an odd case, because when missing *Option 1, then the emulation screen was blank. So i'm pretty much interested in finding more about these 2 options of Client Access/iSeries Access :-

- 57xx XW1 *BASE
- 57xx XW1 *Option 1

What are the exact components inside each option, that control the functions of connection, emulation display, etc ...

i've search thru lots of resources but couldn't get what i'm looking for. HOpe all of u could shed some lights ... thx !
