vt220 screen refesh problem

[Joeri Belis]

Hi list,

 

We run a progress character application under vt220 emulation in screen.

Work great but one major problem

 

When the application changes a charater window ( overlay previous windows with A second window ), this is not refreshed properly.

 

We sometimes see info from the previous screen.

 

I do not have this in my putty emulation but i do have it on the handheld terminals Running telnet in vt220.

 

I tried "allpartial off" but that does not fix it.

 

I have read about setting some vt220 termcap parameters. Any idea what to look for Or try?

 

Joeri
