NOTES:
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 DB25 side in above diagram. If
this is the case, the printer should be set to SSD+.
Some Unix operating systems require carrier to be present. If this is the case, the forcedcd
parameter will need to be turned on for this port at the host.
