Mr. Edwin Lim <[EMAIL PROTECTED]> now has the 'Clever Inight Award'.
How right you are (see below for his original suggestion:):
Try:
if( Outlen ){
len = Write_read_timeout( Outlen, Outbuf, timeout );
Init_outbuf();
} else {
len = Read_status_timeout( timeout );
}
DEBUG3("Do_waitend: len %d", len );
X if( len < 0 ){
X /* we have an error - timeout */
X break;
X } else {
X /* we have something back, so we are happy */
X time( &interval_t );
X time( &start_t );
X }
Lets see what this does:
If Outlen > 0, then we use the 'Write_read_timeout'.
This will do a select() on the output, and if there
is pending input, return a positive value.
So len >= 0, and we will reset the timers...
If Outlen == 0, we use Read_status_timeout.
If it DID read some status then it returns
a positive value. If it gets EOF or times out,
it returns -1.
So this might/should/hopefully fix the problem.
Could you please try this?
Sigh...

See above, good idea!
