Has anyone ever used the Hayes Smartmodem 1200 ? I tried
to but couldn't get it to work. I connected the RS232c cable from
the modem to the Dispatcher, which was placed into slot number 2.
I had pin 4 of the Dispatcher up because the mainframe to which I
will be connected to is 1200 baud. I then turned to page 2-9 of
the Hayes "Smartmodem 1200 Hardware Reference Manual", and tried
the initial checkout. The response should be "ok", but I got
"syntax error". Even though I got this message, I was able to
dial out and hear a computer tone, but unable to received any
prompts from the mainframe. The mainframe is for half duplex.
To dial out I used "AT Ds" and to call the modem typed "PR#2".
Any solution on how to access a computer with this particular modem
and Apple IIe computer will be most helpful.

I'm using a Hayes 1200 Smartmodem on my II+ with no problem, with the Apple SuperSerial Card. Although I'm now driving it (them) with my own little assembler program (so I can handle x-on and x-off and run the printer) I originally started with just the terminal-mode ROM code in the SSC. As I recall, it was important to get the baud-rate set right on the SSC (the Hayes detects what baud you are using when it sees the AT) and to get parity right, 'though I'm not sure how critical that was. The other point was to start the SSC with IN#3, not PR#3 -- that may be what you need too. I don't know if the IIe has hardware scrolling on the 80col screen (I assume not) so to run at full 1200 you have lower the screen window a few lines or you'll lose characters at the beginning of lines.
