|
|
I use serial interrupt routine to accept info from Serial.
The serial interrupt routine gets control for each byte if info and puts into RAM, it might detect Newline charater and set a bit, when transmition is over, main program tests the bit and if set evaluate received information.
I am not very good at bascom, it might be a competent bascom statement to do the work instead. |

Hi achzoll,
I am thinking that you don't have problems, because commands that you were used working just like you said.
So, if you want to use Inkey statement you must write routine that will wait for strings that are comming and analyse them. |

Bascom help says about Inkey:
| Quote: | Action
Returns the ASCII value of the first character in the serial input buffer.
Syntax
var = INKEY()
var = INKEY(#channel)
Remarks
Var Byte, Integer, Word, Long or String variable.
Channel The channel number of device
If there is no character waiting, a zero will be returned. |
So, it says about character, not string. You must intercept each byte of a string separately.
(I my be wrong.) |
