I am having some difficulty using uEmacs 3.10 under X
windows. I am running Esix V.3.2 rev D. The problem has to do
with how escape sequences are being handled. When using uemacs
without X windows all appears to be working fine. The cursor
(arrow) keys are handled properly. Under X windows I was finding
that the escape sequences were not being handled properly. The
escape character was being eating along with the '[' character,
leaving the A, B, C or D on the screen.
When looking at the code I increased the count variable
in the mttgetc function listed below. The escape sequences
started working when I raised the count value up to 4000!!! Does
X buffer escape sequences. Running through that for(;;) loop
4000 times takes about 1 second real time.
Does anybody have any idea on what is happening?
================================================================
/* get a character with timeout */
mttgetc()
{
struct termio tset;
int status;
char c,c_eof,c_eol;
int i,count;
long trns;
fcntl(0,F_SETFL,O_NDELAY);
for(count=150; count != 0 ; --count) {
i = read(0,&c,1); /* get a character */
if (i == 1) /* got a char */
break;
}
fcntl(0,F_SETFL,0);
if (i<= 0) /* timeout error */
return(-1);
i = c;
return(i & 0xff); /* return character */
}
================================================================
Thanks for any help.
