* HS-Modem before MiNT -> MiNT's devices works properly (you need this if
you're using any unix-ports that use the serial-port, like pppd).
* HS-Modem after MiNT -> RSVF-apps (Connect, IConnect, STiNG) works

It has "always" been normal. And needed.

This is done because MiNT actually use the RSVF-routines in it's own
devices, and if the RSVF-cookie was present it's possible for RSVF-clients
and tty-"clients" (e.g. pppd) to use the same port at the same time. If you
want to work around this you can either use a small program called "rsvx"
(you must run it twice - before MiNT where it makes a copy of the
RSVF-cookie, and after MiNT, where it renames that copy to RSVF), or you can
load mint.prg in a binary editor and replace the second occurence of the
string "RSVF" (please check spelling/case before you do this) with any other
4-byte string. This prevents MiNT from skipping the RSVF-cookie when it
creates it's new cookie-jar.

But be careful when you do this - if you by accident run a RSVF-app while
using pppd or vice versa you'll most likely get into trouble.

These use the tty-interface, not the RSVF-cookie. But the tty-devices use
the RSVF-routines, that's why they work so well.

Btw. the easiest way to avoid all these troubles is to use Frank's new
serial-devices. They install both tty- and RSVF-devices, and so far I
haven't had any problems with it (only tested on my Falcon though). The best
thing about them is that you can remove HS-Modem :-)
