NAME

xisdn − ISDN toy telephone for X-Window

SYNOPSIS

xisdn [−toolkit options] [−e]

DESCRIPTION

xisdn is a “toy telephone” for X Window System.  It is operated with the left mouse button or the keyboard.  The key assignment of each function is defined by tty(4) key assignment (erase: Correct, kill: Clear, intr: Disconnect).  And Return key is used to make a phone call or to accept an incoming call. 

To make a telephone call, click the number and press the Call button.  A star ‘∗’ is interpreted as escape for subaddress.  While dialling like this, corrections can be made by pressing Correct or Clear. 

Subsequent use of the number buttons will send additional dialling information (not supported by all ISDNs) or multifrequency tones. 

Buttons F1 to F4 and keys F1 to F10 fetch telephone numbers from the speed-dial file .isdn_no.  Place frequently used numbers in this file, one per line. 
xisdn searches for .isdn_no in your home directory and then in the current directory. 

Sample .isdn_no file:

        # One Touch Dial
        #
        3123−4567            # my home
        −#8300               # voice mail service
        5678−5678∗17         # subaddr = 17
        012−345−6789         # office
        001−1−700−1234567    # US

Answer accepts an incoming call.  Incoming calls sound the bell and rock the icon. 

Disconnect terminates a call.  It can also be used to reject an incoming call. 

Redial of a number is possible within 10 minutes, provided that no other calls have been made in the meantime.  As an additional discretionary measure, use the Clear button at the end of the call to erase the redial number. 

Phone Directory menu popup a window for the telephone directory based on the file .isdn_phone_bool.  Place frequently used numbers in this file, one per line, name and phone number, with separator ‘,’ up to 100 lines. 
xisdn searches for .isdn_phone_book in your home directory and then in the current directory. 

Sample .isdn_phone_book file:

        # Telephone Directory
        #
        T.Yamada, 06−123−4567
        H.Sato, 3987−6543
        J.Yamamoto, 03−5678−1234∗12         # subaddr = 12
        Sony, 03−3448−2111

Depending on the environment variable LC_MESSAGES or LANG, messages will appear in English or Japanese.  The option −e forces English style messages.

BUGS

Calling a toll-free telephone number on some ISDNs does not change the call status to Connected.  In this case, the message CALLING is still displayed even though the connection is established.
