Topic: MSComm32 Lockup
|
| By: Guest | Posted on: Apr 18 2010 at 03:41:05 PM | | I have a question about your post on Mscomm32 locking up. We are using Mscomm32 to simply send text to a Closed Circuit TV. We are not using any handshaking and simply want to sent the text and move on. if the text is received great but if not no big deal. we do not want to lock our point of sale terminal. we have used this technique for years but started running into issues recently where the app would still lockup for exactly 60 seconds. If the problem we are seeing is what you posted on the MsComm32 will your Comm32 solve this issue? Basically, we simply want to send text to the port and move on without waiting for any response. | |

The length of time depemds on the number of characters in the buffer.
In our case switching to Comm32 did solve our problem. | |
