ON COMSET GOSUB
Chapter —Program Instructions
Purpose Statement for branching to a subroutine, when the background reception
of data on the specified communication channel is interrupted.
Syntax ON ↔ COMSETGOSUB|
is one of the following communication channels:
0 = "console:"
1 = "uart1:"
2 = "uart2:"
3 = "uart3:"
4 = "centronics:"
6 = "usb1:"
7 = "uart4:"
8 = "uart5:"
/ is number or label of the program line to be branched to.
Remarks This statement is closely related to COMSET, COMSTAT, COMSET
ON, COMSET OFF, COM ERROR ON/OFF, and COMBUF$. It
is used to branch to a subroutine when one of the following conditions
occur:
- End character is received.
- Attention string received.
- Max. number of characters received.
These three parameters are set for the specified communication channel by
a COMSET statement.
Examples In this example, the program branches to a subroutine for reading the
buffer of the communication channel:
1 REM Exit program with #STOP&
10 COMSET1,"#","&","ZYX","=",50
20 ON COMSET 1 GOSUB 2000
30 COMSET 1 ON
40 IF A$ "STOP" THEN GOTO 40
50 COMSET 1 OFF
.....
.....
1000 END
2000 A$= COMBUF$(1)
2010 PRINT A$
2020 COMSET 1 ON
2030 RETURN
