OPEN COMMS USING

Hi to all,
I'm not a Superbase developer, but I need to solve a problem with a program 
developed with Superbase.

My problem is with one serial print and always I get the following error 
from SBRTS: "Serial Port don't available".

I'm sure that the error is in this line:
OPEN COMMS USING n_com%,9600,0,1,8

I think but I'm not sure that the problem is with "n_com%" var.
Can anyone send me correct code line to print on COM1?

Thanks a lot. 

I'm not certain, but perhaps the problem is really that the port is in use for
something else. Can you try printing to a different port?

You could trap this error and change the port in the code, something like:

  ' use n_com%% (two percent signs) to force integer value
  SET ERROR OFF ALL
  limit%% = 4 ' set to limit of COM ports, whatever it is
  n_com%% = 0
  WHILE NOT (done%% OR n_com%% > limit%%)
    CLEAR ERRNO
    n_com%% = n_com%% + 1
    OPEN COMMS USING n_com%%,9600,0,1,8
    IF NOT ERRNO THEN done%% = - 1
  WEND
  SET ERROR OFF ALL
  IF done%% THEN REQUEST "COM" + STR$(n_com%%,"9") + "
opened successfully" ELSE REQUEST "Sorry!"

Superbase 2 only supports Com1 or Com2.  n_com% can only be 0 for Com1 or 1 
for Com2.  Any other value would produce a "Invalid Error" and not the
error 
you are receiving.  Peter is correct - your port is being used by another 
program.
