Hello!
I'm a happy owner of Silent 700. I bought this thing yesterday for
20 FIM (approx. $3) and it looks spanking new! Really nice.
Anyway it's model 745 and it has an acoustic coupler and a DB15 (male)
connector. I browsed through some classiccmp mails from retrobyte
but I was left a bit confused. Is the 15-pin connector RS-232 or is it
current loop ? (keeping my fingers crossed for RS-232!)
I've also read that you can set different options via the internal jumpers,
does anybody have any idea about those ?
It had a loopback connector on the DB15 connected like this:
2->11
3->13
8->12

The one that I had was. But there might be a jumper for current loop.

I no longer have access to one, nor the manuals.
But I MIGHT still have some RS232 cables for it.
The one that I had, the loopback connected the RS232 compatible terminal
with the RS232 compatible modem. There was a jumper inside that
eliminated the need for the loopback plug, but I used it as a printer, and
used the modem with a TRS-80. That required some special cables to bring
the terminal signals and the modem signals out to DB25s.

I hacked up a cable to use it as a terminal to an HP 9000/380, the
pin-outs had been posted here earlier (stupid me). Next thing to do
is get the acoustic modem to work, maybe like this:
Acoustic modem 680 Ohm 1/2 W + 12V - Zyxel
--------------/\/\/\----------|'|'|'|'--------- Red
----------------------------------------------- Green
(Stolen from www.epanorama.net)
(Simulated line, normal telephones are at least twice as expensive
than cell-phones around here)
I just need to whack the Zyxel a bit to start handshaking
blind.
