16F877 HSERIN problem with 3th party software

[mister_e]

I may have some time to investigate about Modcom... if I had the link for it

It's certainly not down to hardware but how PC software behave.

Hi all

I tried the following to exclude some hardware issue

Took another PC with another comport, just to be shure

On my Easypic4 board I checked that no additional Pull-up or down's are available

When I disconnect the MAX232 serial driver the initial state of RC6 = High,
RC7 = Low
When I reconnect the MAX232 RC6 and 7 becomes High
So all looking normal

Then when I measure with my scoop on RC7 with the terminal program running
(so the command RAD0 (cr) is working fine) I see no difference when I run
for example MODCOM

Can anyone try to use MODCOM with a simple program using a serial command
To see if it works at your end
Use HSERIN/HSEROUT 19200 8N1 and a hardware driver like the MAX232

Looking forward !!!
