Can someone please clarify the wiring on the QL Serial ports on the German and US QLs where a 9 Pin DIN was used instead of a BT style plug?
Dilwyn's site says that the same pins were used as on the BT style plug, but GND (pin 1) appears wrong: 1 GND signal ground 2 TxD output 3 RxD input 4 DTR (=RTS) ready output 5 CTS ready input 6 - +12V I am asking as someone in the USA needs a printer serial lead to connect their QL and Sinclair QL-800 Printer. I was wondering if I could use the Z88 serial lead, which is wired as: 1 - unswitched +5v at 10 uA output 2 TxD transmit data output 3 RxD receive data input 4 RTS ready to send output 5 CTS clear to send input 6 - reserved for future use 7 GND 8 DCD data carrier detect input 9 DTR switched +5v at 1mA output -- Rich Mellor RWAP Services URL:http://www.rwapsoftware.co.uk URL:http://www.rwapservices.co.uk _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
