[RTTY] Re: ÄRTTYÅ RE: RITTY BLASTER Environment variable

[Jan Palmquist]

I use

SET BLASTER=A220 I5 D1 H5 P330 E620 T6

Used on three different computers, with
SB32PnP and SB64AWEPnP boards.

I have once known what the H, P and E parameters
mean,  T is the type/generation of board.

On an IBM TP600 laptop I have succeded to get Ritty to
run with:

SET BLASTER=A220 I5 D1 T4

But I am not sure it runs well, it seems to have some
problems to handle the MUX, but it decodes and transmitts
RTTY.
