2. Unplug Wifi modem USB power cable connected to Retro Wifi SI modem.
3. In Striketerm set Modem type to “UP9600”.
4. Set Baud rate in Striketerm to “1200” & go to Terminal screen.

C64 UP9600 can achieve 9600 baud but we recommend using 4800 for more reliability.
This Commodore 64 and/or Commodore 128 adaptor enables connection of our Retro Wifi SI or other 9 Pin rs232 serial devices to your C64/C128 User Port (such as linking to PC serial or null modem cables etc).
Commodore 64s and Commodore 128s don't actually have a "standard" serial rs232 port (despite having a port labelled Serial on the back!) so the Simulant C64/C128 User Port to rs232 serial adaptor adds that extra port and functionality to your C64 or C128. This enables serial devices or connections to your Commodore computer.
- 3D Printed recyclable plastic, comes as standard in Grey but also available in black/white (see photos - choose colour when adding to cart).
- Adds a standard 9 pin serial DE9 RS-232 connector to your C64/C128(or 25 pin serial DB25 with the use of one of our adaptors here: www.simulant.uk/shop/9-pin-serial-DE9-RS232-connector-25-pin-DB25-adaptor).
- Powered internally by the Commodore's User Port - no extra wires needed.
We offer two versions of the C64/C128 User Port to rs232 adaptor
1. Simulant C64-UP9600 to RS232 Adaptor is designed mainly for the Commodore 64 to take advantage of the UP9600 software terminal drivers (such as StrikeTerm2014 includes) that allow a faster 9600 baud speed. This adaptor does also work with C128 machines but has incompatibility with some external disk drives.
UP9600 interferes with Burst Mode on the Commodore 128. So if you choose this adaptor to allow faster speeds you won't be able to use any disk drives with the C128 that have Burst Mode, such as the 1571, 1581, or CMD drives etc. If you don't use disk drives or peripherals with Burst Mode then the UP9600 adaptor should still work fine on C128 computers.
2. Simulant C128-User Port to RS232 Adaptor works with both Commodore 64 and Commodore 128 computers at the standard User Port rate speed of up-to 2400 baud. 2400 baud was the default baud rate or speed that Commodore 64s and 128s were designed to use serial communications at.
