No pulses.
You're probably thinking modem signals where the frequency shifts
according to bit state.
The RS232 voltage goes high or low for the duration of the bit time.
The reader is supposed to wait for the middle of the bit time to read
the value. This gives the signal the maximum anount of time to
overcome line capacitance, and achieve a non-ambigous signal state.

No, then it really would look like pulses.
The start and stop bits are both high. So a 0 looks like goal posts.

Doesn't the OEM have windows drivers for this?

I get the feeling this is ancient hardware and MS isn't going to allow
very nice support for it.

You could also try sending a "break" signal.
It's been too many decades, and I never used them, but perhaps this is
the signal the OEM contemplated being sent.
I no longer have my hardware manual for the UART, but a communications
library says that a Break is  spacing (0) for more than a character's
time.  It doesn't say how much more, or if it spaces for wall-clock
time, or just a bit more than a char time. In any case, I don't think
it would have any start/stop (high) bits.
