NOTES:
Altpin should be turned off when using this cable.
This cable utilizes the DTR signal of the terminal/printer for hardware flow control (RTS/CTS).
Okidata printers may use SSD (pin 11) instead of DTR (pin 20) on Term/Prn DB25 side of above
diagram. If this is the case, the printer should be set to SSD+.
