Subject: ARA-script for Telebit T3000

! "Telebit T3000 Modem 11/11/91" JFK
! 11/14/91 JFK - Added a ton o' comments...
!
!
@ORIGINATE
@ANSWER
!
! Talk to the modem at 19,200 bps. the T3000 should auto-baud this
! unless the user has locked the port to a particular speed. If it
! locked to a different speed, the user will need to change that.
!
serreset 19200, 0, 8, 1
!
! First recall the factory configuration
! F9 is the built in preconfigured setting for CTS/RTS handshaking.
! Since it's possible for the user to modify F0 parameters, this is a
! little safer.
!
! AT&F9 sets:
! &C1 - DCD is on after connect
! &D2 - DTR on/off disconnects
! S58=2 - Use RTS/CTS flow control in full-duplex mode

! Turn off auto answer and echo, and set it to dial fast...

! &D3 - DTR on/off resets modem

! Next, disable MNP and error control
! turn on internal buffering (for V.32bis),
! and extended result codes (CTS/RTS flow control was set when we
! issued &F9, so we don't need to
! do it here).
!
! S180=0 - Turn off all error detection/correction (ARA does MNP and
! compression itself. It needs these turned off in the modem).
! S181=1 - Turn *on* DTE <-> line buffering if there is no error control
! (which there is not). Since we will be
! talking to the Mac at 19,200 bps no matter
! what speed we connect at, we need this on.
! X2 - Issue extended result codes. This will display busy, connect XXX, etc.
! X2 will say "CONNECT XXX" Where XXX is the line speed. We need this
! so we can tell ARA what speed we are really communicating at
! (for timing)

! Notice that all we do for different connect speeds is issue a
! "CommunicatingAt" command. Remember, we locked the interface speed
! to 19,200 bps so we don't want to reset the serial speed after we connect.
! CommuicatingAt tells ARA what the actual line speed is so that it
! can set it's timers appropriately. I guess your performance would be
! sub-optimal if you don't set this...
