How would one go about making/getting a a coco3< ->pc null modem cable? is
it possible to wire one up to the serial port, without a rs232 pack? if
not, where could i get/make an rs232 pack, and any software to go with it.
PS, I’m not running any OS, just the BASIC shell i think its called
RSDOS sometimes, not sure…but i do have a “VIDEOTEX” pack…
How much is this OS9 running?

I made a COCO RS-232 pack several years ago after buying the service
manual.
It’s actually a pretty simple piece of equipment. If I can find my old
service manual
I’ll xerox a copy and send you the diagram.

Hi Kevin –
I too would like to have a pack with my CoCo equipment I’ve asked but
no one has one for sale
Could you post the RS catalog # of the service manual?
Tandy service/parts might still have some in stock.
Thanks,

All you need is the catelog number of the RS-232 pack.
Call 1-800-THE-SHACK or visit a local store and order
the service manual. It shouldn’t be more than $5 or so.

Rick Ulland pulland [at] omnifest [dot] uwm [dot] edu makes and sells a high speed
RS-232 pak for the CoCo. It uses a 16550 chip which is much faster and
has a larger buffer than the old ACIA used in the Tandy paks. Last I
remember these were about $80, but well worth it. Will easily run 56K
baud.

The “UART” in the coco interface would run to 56Kbaud
but the coco wouldn’t run that fast. I was using it to
transfer files from my coco to my PC and the effective
throughput was only about 12kb or so.

Rick has developed the drivers for OS-9 that take advantage of the
larger buffer of the 16550 and the fewer interupts needed to increase
the throughput dramatically.
