VP5300 and L100 - FAQ and Notes

About COM ports:

When using the C++ Universal SDK with VP5300 via RS232, turn off the external LCD messages (to remove the redundant LCD messages). It can be done by sending the NEO command 0x01-05 with the data 0x1105 by Windows USDK demo. I believe the customer had problem connecting to VP5300 by RS232 on C++ demo, because the port number was wrong. Please note that the port number (used by both Windows and Linux) is not the COM number. Normally the port number is the COM number subtracted by 1 for Windows. Please see the table below:

port nr.	Linux	windows

port nr.	Linux	windows
0	ttyS0	COM1
1	ttyS1	COM2
2	ttyS2	COM3
3	ttyS3	COM4
4	ttyS4	COM5
5	ttyS5	COM6
6	ttyS6	COM7
7	ttyS7	COM8
8	ttyS8	COM9
9	ttyS9	COM10
10	ttyS10	COM11
11	ttyS11	COM12
12	ttyS12	COM13
13	ttyS13	COM14
14	ttyS14	COM15
15	ttyS15	COM16
16	ttyUSB0	n.a.
17	ttyUSB1	n.a.
18	ttyUSB2	n.a.
19	ttyUSB3	n.a.
20	ttyUSB4	n.a.
21	ttyUSB5	n.a.
22	ttyAMA0	n.a.
23	ttyAMA1	n.a.
24	ttyACM0	n.a.
25	ttyACM1	n.a.
26	rfcomm0	n.a.
27	rfcomm1	n.a.
28	ircomm0	n.a.
29	ircomm1	n.a.
30	cuau0	n.a.
31	cuau1	n.a.
32	cuau2	n.a.
33	cuau3	n.a.
34	cuaU0	n.a.
35	cuaU1	n.a.
36	cuaU2	n.a.
37	cuaU3	n.a.

So if VP5300 is on COM11 under Windows, the port number will be 10.
