Beautiful one day,
Perfect the next!
Brenden, The N in the string ATDTN is a command to the modem to try 'auto
reliable mode', and to connect in 'normal' mode if the other modem cannot
connect in 'reliable mode'. An M would try to connect in 'reliable mode' only,
and fail if the other modem could not come up in 'reliable mode'. (This is for
the MICOM modem that I am using, and I believe that other modems would use the
same commands.)

I'm not sure that MNP has been around long enough to have standardized the AT
command set around it. The Practical Peripherals PM2400SA, for example,
doesn't have ATDTN listed in the manual. Instead, you set the mode before the
dialout using AT\Nx, where x is from 0 to 3. 0 is direct mode, 1 is normal
Hayes (equivalent to your ATDT mode), 2 is MNP reliable (equivalent to ATDTM),
and 3 is MNP automatic (equivalent to ATDTN).
Does Hayes have an MNP modem yet? I haven't heard of it. If not, I wonder if
when they release one all other "Hayes compatible MNP" modems will be outmoded
because of their AT defacto standards status?

I guess that, like other 'standards', this one will be decided by the market
place and a committee 😎 . The MICOM also uses an 's' register which can be
set to select the mode. I also haven't heard anything abt a Hayes MNP.
