With the command INPAUX$ the internal RS232-buffer is read and
at the same time cleared. You can find the address of the input-
buffer with XBIOS 14 (Iorec):
The output-buffer can be located with:
If you use INP(1) to read incoming bytes, you should always
check with INP?(1) if the RS232-buffer contains data.
Rsconf (XBIOS 15)
With XBIOS 15 (Rsconf) you can change the RS232-parameters. A
0 - 19200 baud
1 - 9600 baud
4 - 2400 baud
7 - 1200 baud
9 - 300 baud
14 - 75 baud
Use -1 for parameters you don't want to change. Due to a TOS-
bug, you can't use 75 baud, because '14' results in 120 baud.
Also, the old TOS (pre-Blitter age) can't handle hardware
handshake with RTS/CTS-signals. Atari has released a bug-fix that
should enable any TOS to use RTS/CTS. Software handshaking
(XON/XOFF) functions properly. The default after power-up is no
It should be possible to use 75 baud by changing Timer D with
XBIOS 31 (Xbtimer), but I've never tested this:
Change the baudrate:
The text of the articles is identical to the originals like they appeared in old ST NEWS issues. Please take into consideration that the author(s) was (were) a lot younger and less responsible back then. So bad jokes, bad English, youthful arrogance, insults, bravura, over-crediting and tastelessness should be taken with at least a grain of salt.

Due to the fact that these pages are not actually contained in an Atari executable here, references to scroll texts, featured demo screens and hidden articles may also be irrelevant.
