The driver SERIAL.STX supplies driving code for all serial ports 
on Atari computers. It recognizes all standard ports from ST, STE, 
Mega STE, TT and Falcons. The Midi port is treated as a serial 
port too. All additional port hardware, provided OS-level drivers 
are installed into BIOS and an RSVF descriptor exists, is recognized 
too and can be used just like the standard ports. BIOS and RSVF 
installation is done by the HSMODEM drivers, for instance.

The names of the standard ports are as follows :
XXXX ST     :   "Modem 1", "Midi"
1040 STE    :   "Modem 1", "Midi"
Mega STE    :   "Modem 1", "Modem 2", "Ser.2/LAN", "Midi"
TT          :   "Modem 1", "Modem 2", "Serial 1", "Ser.2/LAN", "Midi"
Falcon      :   "Modem 1", "Modem 2", "LAN", "Midi"
Note that you need to do a little hardware work to be able to use 
Modem 1 on a Falcon. The Falcon port that is labeled "Modem" on the 
case is "Modem 2".

If this driver is to be used under a TOS version that does not support 
Bconmap() in XBIOS (if you use a TOS 1.x then this is most probably 
the case) then HSMODEM or an equivalent package *must* be installed. 
To check for this, simply have STinG load this driver, and look into 
the STNGPORT.CPX, or run ConfSTinG from the desktop, or check whether 
Modem 1 is there. Modem 1 should be shown available on every machine, 
even the Falcon. If it isn't on yours, you must install HSMODEM.

If you want to use Midi for serial point to point networking then you 
must install HSMODEM too. Note that you won't find a Midi entry in 
STNGPORT.CPX or ConfSTinG if you haven't got HSMODEM installed. Do not 
confuse this with MidiNet, which is a Midi based ring network that 
brings it's own driver, as HSMODEM MIDI.PRG can't be used for it.

If HSMODEM is used on a TT or Mega STE to control the SCC ports 
("Modem 2" and "Ser.2/LAN") then the HSMODEM SCC.PRG variable "LANBIT" 
should be set to "Yes".


Only for programmers and users of the ConfSTinG configuration tool :
From the flag longword inside the port structures are only 3 bits 
used so far. These are :
Bit 0  :  Use SLIP (0) or PPP (1)
Bit 1  :  If (2) use Van Jacobson Header Compression
Bit 2  :  If port is "Ser.2/LAN" : Use LAN (1) or Serial connector (0)
All other bits are reserved and to be cleared.
