CBM15 V012 has been released to CSDB, and is currently available for download. http://csdb.dk/release/?id=143468 CBM15 is a telecommunications software, that facilitates direct two-way communications between a Commodore 64 computer and a Teletype Corp. M15KSR (or any other compatible machine). Note that CBM15 follows the 5/N/2 serial protocol, at a fixed line speed of 45.45 baud (22mS signalling period). As with any of these PC-to-TTY setups, an external RS-232 to Current Loop converter is required. This is an initial release, and upcoming releases will add new features and correct a bug or two. So.. am I the only one on the list(s) with a C-64 and an M15 on hand? If you have the required hardware, please give it a try - so far, I've had no feedback from any other 'real' M15 owner.. Thanks!
