where
REG is A - K (the registers in the ARD 2650)
COMMAND can be a 2-chars command, but mostly 1-char commands.

EG:  AR:255<cr>  // AR configures DDRA to out- or in-put , depending on the parameter - (here 255 / 0xff) .

AI:0<cr>  Read port A input (actually return content of ARD2560 port A inputregisterinput register)
   
AO:<number><CR>   Send Number to port A (and return result to D-7 ).

......

All those command are valid for RegReg A to Reg K.

 if (char (pport[0] == '*' ))  // '*' can be 'A' to 'K'

the responsetime increases to appr. 2 sec's .

 if (char (pport[0] == '*' ))  // '*' can be 'A' to 'K'

(sorry there's no comment !) The response time increases to appr. 2 seconds.

Thanks for Any help.(sorry that there are no comments!)

here'sHere's the Codecode:

where REG is A - K (the registers in the ARD 2650) COMMAND can be a 2-chars command, but mostly 1-char commands.

EG:  AR:255<cr>  // AR configures DDRA to out- or in-put , depending on the parameter - (here 255 / 0xff) .

AI:0<cr>  Read port A input (actually return content of ARD2560 port A inputregister)
   
AO:<number><CR>   Send Number to port A (and return result to D-7 ).

......

All those command are valid for Reg A to Reg K.

 if (char (pport[0] == '*' ))  // '*' can be 'A' to 'K'

the responsetime increases to appr. 2 sec's .

(sorry there's no comment !)

where
REG is A - K (the registers in the ARD 2650)
COMMAND can be a 2-chars command, but mostly 1-char commands.

EG:  AR:255<cr>  // AR configures DDRA to out- or in-put , depending on the parameter - (here 255 / 0xff) .

AI:0<cr>  Read port A input (actually return content of ARD2560 port A input register)
   
AO:<number><CR>   Send Number to port A (and return result to D-7 ).

......

All those command are valid for Reg A to Reg K.

 if (char (pport[0] == '*' ))  // '*' can be 'A' to 'K'

The response time increases to appr. 2 seconds.

How to speed appication up (if possible)

I have an ARD 2560, which I communicate with through a special written Delphi 7 program (USB handling is done in the D-7 program).

I use the command syntax:

<REG> <COMMAND) <:> <NUMBER> <CR>

where REG is A - K (the registers in the ARD 2650) COMMAND can be a 2-chars command, but mostly 1-char commands.

EG:  AR:255<cr>  // AR configures DDRA to out- or in-put , depending on the parameter - (here 255 / 0xff) .

AI:0<cr>  Read port A input (actually return content of ARD2560 port A inputregister)
   
AO:<number><CR>   Send Number to port A (and return result to D-7 ).

......

All those command are valid for Reg A to Reg K.

The response time from transmit (d7) to I ("D/7") get the answer is approx. 1 1/2 second. I have a feeling that my code is a big, big kludge (it actually works), but I would like any advice(s) to to improve code // speeding it up.

If I drop the line:

 if (char (pport[0] == '*' ))  // '*' can be 'A' to 'K'

the responsetime increases to appr. 2 sec's .

(sorry there's no comment !)

Thanks for Any help.
