Hints to setup your ZyXEL U-1496 

Here are some guidelines to help you setup your ZyXEL
modem and software.

1.   High speed modems operate differently from the 2400
     buds and lower speed modems.  Because of data
     compression and error correction functions, the actual
     communication speeds between the telephone line and
     the modem and between the modem and your
     computer are quite different.  In most cases, setting
     your software to communicate at the modem speed is
     not enough.  We recommend you to set your software
     at speed of 38,400 or 57,600Kbps if you have 16550
     UART. (ZyXEL U-1496B Internal model has a 16550
     UART)

2.   All the ZyXEL U-1496 series have the capability of
     auto handshaking which would adapt to different
     speeds.  In most cases, it will talk to 1200, 2400, 9600,
     14400 buad modems without changing the settings. 
     Therefore, we advise you to set your communication
     software at fixed 38,400 or 57,600 Kbps. and turn
     "Auto Buad Rate Detect" off.  

3.   Most communication programs let you select different
     communication speeds for each entry in the dialing
     directory.  For high speed modems, we suggest you
     revise the speed of all entries to a fixed 38,400 or
     57,600 Kbps.  This is the speed your computer will talk
     to U-1496, and the U-1496 will then decide which
     speed it should communicate with the modem at the
     other end.

4.   Most communication programs use the result message
     which the modem returns to the software when
     connection was made to determine the speed of the
     communication.  Since the "Auto Buad Rate Detect"
     has already been turned off the "Result Message"
     settings in software is no longer important.  We
     suggest you to keep "Connect" only in the result
     message setting section of your communication
     software.

5.   Flow control is very important in high speed modem
     communications.  We suggest you use "Hardware Flow
     Control" or "RTS/CTS Flow Control" with ZyXEL
     U-1496, since it is the most efficient and is also the
     manufacture default setting.

6.   When you first start up the modem please make sure
     to issue a command, "AT&F" to your ZyXEL U-1496
     prior to doing anything else.  This will reset the modem
     back to manufacture default setting.

7.   We have developed drivers for some popular
     communication software.  You can log in to our BBS at
     886-35-787045 to find out if we have the drivers for your
     communication software.  If you are unable to find the
     driver please leave a message for our SYSOP. It is
     possible, we might be able to have the driver ready
     for you within a week.
