- I'm using Spectre GCR to do a lot of Mac word processing, as well as
- downloading things from my local Internet provider. I rely on the fact
- that the Spectre software turns the Mac serial printer port output into
- parallel output on the ST's printer port. Running MultiFinder I can print
- in the background over the printer port and download at the same time. I
- want to go to a serial printer (well, it's more complicated than that, but
- I'll explain later), and I'm wondering if I can keep using the printer
- port, running the output through a parallel-serial converter.
-
- Has anyone used a parallel to serial adapter on the Atari printer port to
- drive serial devices?
-
- I know Spectre internally converts the Mac OS's serial output intended for
- a Mac printer port into parallel output, but is anything done for input?
- Is this even a reasonable question? (I don't know of any bidirectional
- parallel devices, although I have seen ads for bidirectional
- parallel-serial converters.)
-
- The GCR manual doesn't go into a lot of depth as to the nature of
- Spectre's internal serial-parallel conversion. A one-way (output only)
- conversion would be sufficient to drive parallel printers, but wouldn't
- work at all if I tried to hook up a serial device that needed to be able
- to talk back.
-
- (Actually, my ultimate goal is even more complicated, involving directing
- Spectre printer output through a null-modem cable into a 486 box running a
- Unix clone, where a daemon process will handshake like a LaserWriter,
- accept the PostScript output, and pipe it to GhostScript, a free Gnu
- Public Licensed PostScript emulator... but that's some time in the future)
