Given all the discussion about V.32 modems, let me share my initial
experiences with my just arrived Intel 9600EX modem.

I connected the 9600EX to my PC and ran Procomm-Plus. Literally I
took the modem right out of the box and didn't reset any of the
configuration parameters from their factory default. The modem
automatically followed any interface speed that I set in Procomm.

There was no problem setting the interface speed to 38.4kbps and
dialing into a 2400 speed MNP5 Multitech modem. The reliable connection
was established with no problems.

Next I called long distance to a Robotics HST/DualStd. Again I got a
'reliable' connection with no problems.

I called long distance to a Hayes Ultra 9600. It took three calls to
get the connection established, however once it was established it was
completely solid. Perhaps the first two calls took a marginal route.

I was somewhat surprised (due to lack of prior experience with dial
9600 speed modems) at how long it takes for these modems to establish
connection after the phone answers. The average time was 20-30 seconds.
Is this normal?

So my initial experience with the 9600EX has been very good. All the
talk about V.32bis modems makes me wonder if I jumped the gun and
should have waited before buying into V.32 hardware. On the other hand,
since I bought this 9600EX thru the BBS sysop's promotion for half
price, I feel I got an excellent value.

The only minor problem I had was (I think) due to COM port overrun. I
run DesqView. That combined with the 38.4kbps interface speed likely
means I need to get a 16550 buffered UART. The simptom was Zmodem asking
for retransmissions when the modem connection was in fact operating in
reliable mode. When I tried using Ymodem-G the download was aborted on
my end, making me suspect the problem lies between the modem and my
comm program.
