New Post: Setting the Terminal device

Is there a way of me setting which device i'm connecting as? We use a VT100 and when I connect I get a load of text back saying error device not recognized etc.

What im getting back is:

13:32:26: %SET-W-NOTSET, error modifying FTA1880:
13:32:26: -SET-I-UNKTERM, unknown terminal type
13:32:27: [c
13:32:38: %SET-W-NOTSET, error modifying FTA1880:
13:32:38: -SET-I-UNKTERM, unknown terminal type

What im wondering is if I can sort of tell the system im connecting as a VT100?
