Setting Up and Calling Out with the seyon X11 Client

The seyon communications program, by Muhammad M. Saggaf, runs only under the X Window System and has an extensive list of features. Although seyon is not as simple or initially friendly as minicom, it does have the following:

• Built-in help

• A built-in telecommunications scripting language to automate calling up and log­ging in to other computer systems

• A built-in text editor for writing telecommunications scriptsз

• A command-line shell dialog box for running commands, which displays output in the main communication window

• Buttons to set up modem speed, parity, and stop bits

If you created a symbolic link to /dev/modem, the seyon program automatically recog­nizes and works with your modem. All you have to do to call out and connect with another computer is to type your AT command string with the phone number to dial out and connect.

If you need to tell the seyon client the specific device for your modem, click on the Set button in the seyon Command Center window (which appears automatically when you start the client) to bring up the Settings window. Click on the Port button in the Settings window, and type in the name of the device, /dev/cua1 for example, in the Values? window. Figure 9.7 shows seyon and its settings windows.

Click on the OK button, and click on the Close button of the Settings window. If you want to start the seyon program with a default modem speed, number of bits, or parity, edit the file $HOME/.seyon/ . This directory is installed automatically when you install the seyon program. You can make changes to the following lines in the startup file:# set baud set baud 19200

# can be 5, 6, 7, or 8

# set bits 8 set bits 8

# can be 0 (= no parity), 1 (= odd parity), or 2 (= even parity)

# set parity 0 set parity 0

# can be 1 or 2

# set stopBits 1 set stopBits 1

If you need help when using the seyon program, you can click on the Help button in the seyon Command Center window. A window pops up with the seyon manual page, and you can scroll through the text for help (the help screen is shown in Figure 9.7).
