+FPTS:n Receive page transfer status response; refer to +FPTS=n command. +FTSI:"String" Report remote ID response TSI. +FVOICE Transition to Voice response. The Class 2 Flow Control Flow control is necessary to match the DTE-DCE date rate to the line signaling rate while transmitting or receiving Group 3 (T.4) data. In Class 2 FAX mode, both hardware flow control (RTS/CTS) and software flow control (XON/XOFF) are enabled. Extended FAX AT Commands These commands are unique to the U-1496 series modems. The computer controls the modem through a set of extended fax AT commands and the modem responds with a set of status report result codes. During data state, compressed fax image data is flowing between the modem and computer. The default serial connection speed is 19200 bps and it is higher than the fax link rate. CTS/RTS hardware flow control is used to regulate the data flow. The modem accepts the extended fax AT commands to set modem mode and fax parameters. Besides the extended fax AT commands, the modem accepts all the other AT commands described in Chapter 8. For instance, you can use 'ATD' to make a fax call, or 'ATA' to answer an incoming fax call. When using the extended Fax AT commands, you need to send the command "AT+FCLASS=6" first. Following are the fax related AT commands: Mode Setting #F Set the modem into 'V17G3 FAX' mode, same function as the extended AT command 'AT&N32'. #B0 Set fax receiving mode. The connection parameters and received fax data are sent to DTE continuously following the connect message. (Default). #B1 Set fax receiving mode. The connect messages are separated from the received fax data. The modem sends "CONNECT FAX" and "ZyXEL" first, then it waits for the DC2 character (hex18) to send the fax data. When the modem receives a DC2 from the DTE, it starts to send the fax connection parameters "/SnnnnVnTnRnLnCnP " then the received fax data. In this mode, the modem will wait for DC2 at the beginning of every page. The DTE software should detect the page separator "RTC" then sends the DC2 to receive the next page of fax data. This mode is used with BBS receiving fax. #B2 This mode is for the polling feature of the modem. In this mode, the modem will send a polling signal to the remote fax device to ask to receive a fax from the remote fax device. The received fax data will be sent to the DTE continuously following the connect message. Parameter Setting #V0 Set to normal vertical resolution. #V1 Set to high vertical resolution. #T0 Set to one dimensional coding scheme. #T1 Set to two dimensional coding scheme.

The Class 2 Flow Control
Flow control is necessary to match the DTE-DCE date rate to the line signaling rate while
transmitting or receiving Group 3 (T.4) data. In Class 2 FAX mode, both hardware flow control
(RTS/CTS) and software flow control (XON/XOFF) are enabled.
Extended FAX AT Commands
These commands are unique to the U-1496 series modems. The computer controls the modem
through a set of extended fax AT commands and the modem responds with a set of status report
result codes. During data state, compressed fax image data is flowing between the modem and
computer. The default serial connection speed is 19200 bps and it is higher than the fax link rate.
CTS/RTS hardware flow control is used to regulate the data flow.
The modem accepts the extended fax AT commands to set modem mode and fax parameters.
Besides the extended fax AT commands, the modem accepts all the other AT commands
described in Chapter 8. For instance, you can use 'ATD' to make a fax call, or 'ATA' to answer an
incoming fax call. When using the extended Fax AT commands, you need to send the command
"AT+FCLASS=6" first. Following are the fax related AT commands:
Mode Setting
#F
Set the modem into 'V17G3 FAX' mode, same function as the extended AT command 'AT&N32'.
#B0
Set fax receiving mode. The connection parameters and received fax data are sent to DTE
continuously following the connect message. (Default).
#B1
Set fax receiving mode. The connect messages are separated from the received fax data. The
modem sends "CONNECT FAX" and "ZyXEL" first, then it waits for the DC2 character (hex18) to
send the fax data. When the modem receives a DC2 from the DTE, it starts to send the fax
connection parameters "/SnnnnVnTnRnLnCnP <string><CR><LF>" then the received fax data.
In this mode, the modem will wait for DC2 at the beginning of every page. The DTE software
should detect the page separator "RTC" then sends the DC2 to receive the next page of fax
data. This mode is used with BBS receiving fax.
#B2
This mode is for the polling feature of the modem. In this mode, the modem will send a polling
signal to the remote fax device to ask to receive a fax from the remote fax device. The received
fax data will be sent to the DTE continuously following the connect message.
Parameter Setting
#V0
Set to normal vertical resolution.
#V1

#T0
