Connecting a WIFI modem to the Nabu's serial card

Post by Henry99 »

Hey guys

I was able to go online, on my Nabu, and read today's news

You can do this also as long as you have a WiFi modem and Klyballs serial card

Setup your WIFI modem by enabling FLOW CONTROL using XON and set ECHO to OFF and set BAUD to 1200(higher rates drop characters)

Next attach the WiFi modem to the serial card using a rs232 cable (do not use a NULL cable)

Set the RS1 serial card using the DEVICE command

DEVICE RS1[XON,1200]

Now run the program RS1XFER using this syntax

RS1XFER RT.1200

now connect to a BBS

ATDT BBS. RETROCAMPUS. COM

Choose option 2 for 40 COL no echo

Your NABU is now online!!!

Cool cool. Is this a product for the nabu? Is there a link?

Also, this can be achieved by using the Cloud CPM Telnet command. (viewtopic.php?t=7)

1) Load Cloud CPM

2) Go to User Area #1 (user 1)

3) On the A:1> prompt, type TELNET <remote ip> <port>

I'm looking forward to finding a modem script on one of my floppies that emulates the conversation that I would have between a NABU PC and the Gould SEL that was the NABU headend combiner. I used to upload binaries for the cycle, set them up for the menu. and build the cycle, which for some strange reason took more than 30 minutes.

Also used to download the Astrology and Movie Reviews from King Features for inclusion in the cycle.

I must be confused about what this is. Isn't the "wifi modem" establishing a TCP connection to a remote host? So wouldn't that just be the same as going to A: User Area #1 and typing "telnet <IP address>" ?

ie go to cloud cpm A:, go user area #1, type telnet bbs.retrocampus.com

My interpretation is that while the end result is the same, this is a different way of going about it - the NABU is doing it direct, rather than through an intermediate back-end/cloud system.

Ah I see, thanks :) - just to clarify, there's no "cloud" involved for telnet. It's the same, just uses the internet adapter as the wifi modem. So it's identical in the number of steps to achieve the result. Rather than using the Serial port, it uses the HCCA port (which is serial).
