File Transfer over Serial?

[Machead]

I have a Performa 6360 with ClarisWorks 4 on it, and I have a PC with Windows 98 and PuTTY on it. How do I connect them so that I can transfer files between them? I've looked online, but no connection I've found there works.

6360? If it has OS 8+, throw a USB card in that and use some old FAT formatted flash drives. If not, throw a network card and FTP stuff over. Here's a cheap network card, http://www.ebay.com/itm/222482232228 .

Serial transfers will be fairly slow but you should be able to do it with a terminal emulator that supports stuff like xmodem. Beware though as Windows 98 will break the Mac resource forks making file transfer a pain.

It has 7.5.3. I have a network card, but the only Mac drivers for it are for 10.2.9 and up. (Its Windows drivers go as far back as NT 3.51!) I'm basically committed to serial. I would like to know how to connect RS-232 to Mac RS-422 for the purpose. None of the pinouts I've found online works. I've been using the modem port, if that helps.

I recently used a 8 pin mini din to 9 pin adapter that I found at a thrift store (I think it was originally a Mac plus serial adapter, but who knows) which I then attached to a PC-style null modem cable.  Worked a treat.  No clue what the pinouts are though, sorry.  I do see those md8 to db9 adapter cables on ebay from time to time.

I tried this pinout with ZTerm 1.0.1 and ClarisWorks, but neither works. I cannot transmit characters from the PC, and whenever I type anything on the Mac, in both ZTerm and ClarisWorks, it is just echoed, though "Local Echo" is turned off. It also does this when nothing at all is connected to the modem port. My cable works, i.e. it transmits signals along its length.

Some pinout images and infos here, if it can help :

The pinout at applefool works wonderfully on my 7200, but not on my 6360, where I really need it. This tells me that something is wrong with my 6360's modem port.

 

[Machead]

I found something. My 6360 came with a fax-modem installed. I started up with extensions disabled, and the modem port behaves as it should. There's some Performa software or something interfering with my modem port.

EDIT: It was the "Express Modem" control panel. I disabled it, and the modem port now appears to work.

IIRC, having a comm slot modem disables a serial port, so yeah, having one installed will do that!

 

[rsolberg]

Yup! Installing a modem into a CommSlot, CommSlot II, or into the modem slot on a beige G3 personality card will disable the "modem" serial port on the Mac's logic board. On Macs that shipped from Apple with a modem installed in one of these slots, there is a blank plate or plastic plug covering the "modem" serial port.

Now I have a different problem. I can send characters from my Mac to my PC, but not the other way. The baud rates &c. are set identically on both machines. My PC is putting characters out onto the serial line, but my Mac isn't reading them. Not even anything garbled: nothing at all appears on the Mac.

It seems my modem port is just being stupid: it works just fine with my printer port.
