U-90E Data/Fax Modem 4.6 Helpful Hints for Mac Computers 4.6.1 Special AT Command Settings for Mac For operation with Mac computers, you may use the factory default settings with one exception. You must set the modem to ignore the DTR signal as follows. Type: AT&D0 (set modem to ignore DTR) AT&WZ (saves the settings to power-up profile) 4.6.2 Mac Serial Port When you connect your modem to a Macintosh computer, make sure the cable is a hardware handshaking type. These cables are readily available. Macintosh Lisa model 128 and 512 don't have hardware handshaking. The serial port on these (very outdated) models is provided as a 9-pin connector similar to that of a PC. The serial port on all other Macintosh models is a Mini-8. 4.6.3 Mac Software Tips All terminal programs that make use of the hardware handshaking feature can be used on the Apple Macintosh. Such programs are readily available as PD, shareware or commercial software. One of the most powerful shareware programs available is ZTerm. Fewer programs are available to make use of the ZyXEL's fax features. One program that has found wide acceptance is FaxSTF that can be installed like a printer driver allowing you to send faxes from almost any program which runs on your Macintosh. At the same time it allows automatic fax receiving. This program includes powerful line manager software which makes sure fax software does not interfere with other programs using the serial ports. If the modem is turned off when you start your Macintosh with the line manager activated, the computer may seem to freeze for a few minutes. During this time the line manager software tries to locate and to set up the modem. Turn on your modem before you start your Macintosh to avoid this delay. Basic Modem Operation 4-11
