OctaMED SS rev.2
Auto Flow Control
Twister should be used in a tower housing. "Right, left, top and bottom" is not a usefull description because there are many different towers. Usually there should be a proper hole in the case to mount the serial connector. If there is none you can get a bracket at a computer dealer next to you. Attention: The installation is quite strange compared to the MK1. MK2 has got parts downwards and orientation away from chipmem. If your machine has more than the 22 pins clockport put Twister nearer to the floppy drive.
If you like to use Twister inside the traditional case read on, please.
Twister was done with respect to guidelines and rules of CE and FCC. Allthough Twister is only one component of the system. It's up to you to ensure compatibility of the whole system. For example if there is noise in radio when the machine is running, stop using it!
At the floppy which is comming with the board there is the driver required for Twister. The installation procedure puts a copy of twister.device in DEVS: (Devices) directory and Twisterprefs into PREFS: (Preferences) directory. Twisterprefs was done for compatibility to devices (Modem, TA,..) which don't handle hardware handshake correctly. By default auto-flow-control should be activated since it ensures error-free transmissions and system load is much lower, too. If a soundboard is used it's strongly recommended to leave auto-flow activated!

A connection via modem at 57600 bps to your provider requires a (much) faster connection from computer to the modem. You should choose a bitrate which is fast enough to move the data like 115200 bps. Don't use extreme numbers if your CPU is not fast enough to increase CPS rates at higher bitrate. This may cause a lower CPS (real transmission speed in characters) at a higher BPS rate (max. possible transmission speed in bits including control bits). There is no generic rule because of so many configurations. Check out your optimum!
