Hi
I have a Plus and external SCSI box that started to take notice of recently. The Plus now has 4MB of RAM and a working system disk with 6.1.8, courtesy of Basilisk and a PCI SCSI card on my Linux box.
I'm now taking the next steps of MacTCP + PPP, but I have run up against problems with the serial ports.
I bought http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&rd=1&item=140163948672
but even at 9600/8N1 with no XON or RTS handshaking, I can get no data in or out of ZTerm 0.9 with either modem or null modem cables.
In fact, I even tried just putting a bit of wire between pins 2 and 3 of the RS232 connector but got no echo. Same thing happens with both the Modem and Printer ports (AppleTalk is off - ZTerm let me select the Printer Port without complaint)
Is the serial logic likely to be fried on the board or is there something else I can try? SCSI, floppy, keyboard, mouse, sound and screen on the machine all work perfectly.
Cheers,
Gavin.
