BitWare modem driver file
File type: Various data file
The tx$ file extension identifies a BitWare modem driver file. It is a component used by BitWare modem software rather than a user document.

The tx$ file is associated with BitWare modem devices and software. It stores part of the driver data used by the modem.
Because it is a driver component, the file belongs with the other files in the BitWare installation and is normally accessed by the software itself. It is not intended to be opened or edited as a standalone file.
BitWare products appear to be obsolete and are no longer supported by their developer, so the tx$ format is unlikely to be used in current modem software.
Open the tx$ file only through the BitWare installation that supplied it. BitWare should use the file as part of its modem driver; it is not normally opened directly with a general-purpose application.
The tx$ file is a driver component rather than a document or media file, so it is not normally converted to another format. Keep it with the BitWare installation if the associated modem software still requires it.
