A.19 Sample TSIP Routines
The following sections give sample routines that use command
packet 0x1F and report packet 0× 45 for getting software version
information from the ACE UTC GPS via COM1. Source code for a
working TSIP monitor program is available at www.trimble.com/
support/files.
Sending out TSIP command packet 0x1F
In general, all TSIP packets use the structure TSIPPKT:
#define MAX_RPTBUF 256
typedef struct {
short
cnt; /* size of buf */
unsigned char
status, /* TSIP packet format and parse status */
code, /* TSIP id code */
buf[MAX_RPTBUF]; /* command or report string */
} TSIPPKT;
Communication with the ACE UTC GPS is accomplished through
command routines and report routines. Each command routine use
send_cmd() which supplies the DLE stuffing to the command string
and sends the command to the serial port using the primitive function
sendb().
