i already saw that but it takes the "INPUT" instruction.
That is the normally Bascom instruction.
Of course, this is the simplest way to implement a serial interrupt routine.

Hi.
instead of "$baud = 9600"
use "$baud = 19200"
Anyway you can connect the cellphone (with the serial adapter) to your PC serial port, and use hyperterminal to send command.

Is that right ? |

Makebcd works from 0 to 99 decimal
To convert number greater then 99 a different approach is necessary.

With a single 4094 you can count until 99; simply use makebcd and shiftout statement.
Do not forget to limit your counter to 99.
