[ts-7000] Re: TS7800 COM1 RTS problem

["ray_gardiner" <>]

Hi Harold, 

You are spot on.. thanks for that advice, flipping those bits works nicely.

Here is a quick and dirty shell script that toggles RTS and DTR
on COM1.

#!/bin/sh
#
# Toggle RTS and DTR on TS7800 Com1
#
#disable /dev/ttts0 and ttts1 
poke16 0xe80000c0 0x10e1  
poke16 0xe80000c4 0x10e1

# now we loop toggling bits 13:14 in 0xe800000c
#
while true
do 
        peek32 0xe800000c 
        poke32 0xe800000c 0x1bdc
        sleep 1
        peek32 0xe800000c
        poke32 0xe800000c 0x7bdc
        sleep 1;
done


Much appreciated.

Regards
Ray
