I am trying to read data from a paging receiver which is connected to the serial port. Here is the problem, I can only read/store the first 14 characters that are sent to the device. Here is part of my code:
$ob->lookclear; #clear the buffers
$ob->buffers(4096,4096); #read, write
sleep 1;
until($return ne "")
{
if (($return = $ob->input) ne "")
{
$ob->write ($return);
print "return:$return a";
}
else
{
print "ERROR!! Did not receive a page yet!\n";
}
}#end until
print "return is:$return";
undef $ob;
Is there any way to store more than 14 characters in the variable. Also, any sample "serial port" code would be helpful.
Thanks for your help,
Jason
