I will try to explain the problem as best as possible.
When I enter a command, the response from the mud does not reach me, so for example, if I put the name of the player, the message that I enter the password does not appear.
It is strange because the only way I found to read in this type of cases, is to send anything to my client locally and there if it is updated.
I give an example and sorry for my English:
the mud sends: Character name:
I write: test
There the mud sends me to enter the key, but I cannot read it, for this, in an alias I put a Note ("update")
And there if the following appears in the output:
Password:
update
That is, I see the text that did not come to me from the mud and below my Note.
This only happens to me in character creation, login or very specific situations such as password change.
