- ; SUBJECT : BYE510 FIX
- ;
- ; FROM : IRV HOFF
- ;
- ; DATE : 4 AUG 86
- ;
- ;
- ; NOTE TO SYSOPS: You may wish to put this little
- ; file in your master BYE510.LBR so
- ; it will be available to anybody
- ; downloading that file.
- ;
- ;
- ; Several Sysops have mentioned when using BYE510 they were unable
- ; to properly operate their local keyboard. The fix involves (1) moving
- ; three lines in the MINP2: area and (2) adding three lines plus a new
- ; label in the MSTAT: area.
- ;
- ; The problem occurred when those routines were altered to provide
- ; proper timeout with the METAL BBS program when nobody had typed on the
- ; remote keyboard for some time. METAL was looping while waiting for a
- ; status bit to go high indicating a character could be obtained. The
- ; BYE program(s) had been looping until the character was received. The
- ; METAL program could thus hang up the system for long periods of time
- ; if nobody was typing at the other end.
