Chapter 22 ZyXEL MODEMS AND UNIX Hints for Unix Setups Cable Please consult the documentation that came with your workstation to find the part number of or information on how to make a serial cable for your workstation. The cable should be a hardware-handshaking cable. Please refer to Appendix A for a complete list of signals provided by the modem its serial port. Installation Modem settings Unix environments usually don't like modem responses or echoing of commands. Therefore you should set ATE0Q1. If you plan to install a dial-in line, don't forget to set the S-register S0 to a value other than 0 (e.g. ATS0=2) for auto-answer. Depending on your kind of Unix, the cable and software used, you may have to disable carrier detection using AT&C0. Unix system files If you wish to use your modem for dial-out connections, you only need appropriate software, but no changes to system files are necessary. You need to generate information or activate entries in at least two system files. If you wish to use your modem for dial-in connections, these files are /etc/inittab and /etc/gettydefs. In /etc/inittab, you define which getty to use along with some parameters. The final parameter on the definition line is a tag which points to an entry in the file /etc/gettydefs discussed next. An example for your entry in /etc/inittab might be: s1:45:respawn:/usr/lib/uucp/uugetty -mt60 -r- ttys01 MMULTI The parameter ttys01 should be replaced by the actual name of the used serial port. 22-1
