Card Type	Modem (asynchronous)
Chip Set	Unidentified
Maximum Data Rate	2400bps
Data Bus	Internal/Toshiba bus
Data Modulation Protocol	Bell 103/212A ITU-T V.21, V.22, V.22bis

CONNECTIONS
Function	Label		Function		Label
RS-232-C		CN1		Line in		CN3
Line out		CN2		Proprietary connection to computer		CN4

POWER
Setting	SW1
Auto-start with telecommunication software	Position 1
Serial port in use/modem disabled	Position 2
On	Position 3

PORT ADDRESS
Modem	Serial Port	SW6
COM1 (3F8h)	COM2 (2F8h)	Up
COM2 (2F8h)	COM1 (3F8h)	Down
Only T3100 and T5100 has SW6, T1100PLUS and T1200 are defaulted to COM2, T1600 uses software to determine the COM setting, T5200 uses the SETUP program to set the COM port.
When SW1 is set to position 2 (serial port in use), serial port address is used.

DIAL
Type:	Immediate
Format:	AT [cmds] D<#> [cmds]
Description:	Dials telephone number according to any modifiers included in the string
Note:	Any combination of modifiers can be used to produce the desired dial functions in sequence.
Command	Function
DP	Pulse dialing enabled
DR	Answer mode enabled; originate mode disabled following handshake initiation.
DS=n	Dial stored telephone number n
DT	Tone dialing enabled/Pulse dialing disabled
DW	Dialing resumed following dial tone detection
D,	Dialing paused for amount of time specified in S8 register
D!	Flash function initiated. Modem commanded to go off-hook for specified time before returning on-hook.
D@	Wait for Quite Answer function enabled. Modem waits until a "quiet answer," a ring-back signal followed by silence up to the time specified in S7, is received prior to executing the rest of the dial string.
/	Pause for .125 second
D;	Modem returned to idle state after dialing. The semicolon can only be placed at the end of the dial command.
