How do I create the RS232 objects in software to make use of the COM3 and COM5 serial ports on the Cobra II? The only code I know of is this:
public RS232(int socketNumber); this.rs232 = new GTM.GHIElectronics.RS232(8);
To create the RS232 object, I must pass in the number of the socket. The designer tool will allow RS232 connections to sockets 5,7,8 only, all type U sockets.
There is no U type socket for COM3 and COM5. The COM3 Tx and Rx lines appear on the extender card expansion bus JP2 pins 4 and 6. The COM5 Tx and Rx lines appear on the main board LCD_R4/P2.9/COM5_RXD on socket 3 and LCD_B4/P1.29/COM5_TXD on Socket 1.
