Escape key problem

Escape key problem

[Javier Tarifa]

I don't know if I'm the only one who's experiencing this, but the escape 
key is very slow to respond in dosemu. When I press the escape key I 
have to wait almost half second before the program does what's supposed 
to do. We're accessing it by ssh but the problem also appears on the 
server if we open dosemu in an xterm. Any ideas on how to solve this? 
First I thought that this was linux-related, but then again I thought of 
vim and how you can switch to command mode instantly and without delay 
when you press escape, so I don't know what's the problem

Nevermind, I found that the responsible of this delay is the function 
sltermio_input_pending. I'll try deleting or lowering the wait and I'll 
see how it works.

Hi Javier,
	I think this is related to the fact that the escape key is used to indicate 
the start of a special key sequence(F1,F2 etc) in VT* terminals. I think you 
can prove this by pressing the ESC key twice in quick succession; it should 
only send one ESC to the application. Earlier, around dosemu 1.2.2, I did once 
modify both the terminal program(putty) and dosemu to use the F20 escape 
sequence to generate ESC. This is fine as a one off, but could never be put 
into the core dosemu.

Best regards,

Andrew
