INTRODUCTION TO THE SOFTWARE

4.5.4-POLL, -SIGNAL

These two options control how the host software detects whether or not the user’s code is running. If poll mode is selected, the host periodically polls the target with a REPORT_STATUS command. This takes no additional hardware, but it forces the target to spend instruction cycles responding to the poll. The signal mode avoids this overhead, but it requires that the target set the Ring Indicator modem line before it issues a REPORT_STATUS command. If neither option is selected, the signal mode is selected as a default. On the board, the P1.3 pin of 80x186 processor is used to generate this running signal. Therefore, the signal mode is recommended. (The REPORT_STATUS command is described on page 6-5.)

4.5.5RESET SYSTEM, RES SYSTEM, RESET, RES

This command and its abbreviations reset the entire target hardware system. This command operates by dropping the DTR modem control line. This comes into the target as DSR. After dropping DTR, the iECM-86 software waits about 1 second to allow the target to complete its initialization routines. The iECM-86 warns of this time delay and then ignores input from the host PC until it expires. Unless special precautions are taken in the design of a target system, any data in RAM (including downloaded object code) may be corrupted by the reset. On the board, the RAM contents should not be affected by a reset.

4.5.6DOS

This command enables you to temporarily leave iECM-86 and return to DOS. Once you have suspended iECM-86, you may perform other functions in DOS, including using other software programs such as ASM86, as long as there is sufficient memory to do so.

To re-enter iECM-86, type exit at the DOS prompt. iECM-86 returns with all conditions that were in effect at the time it was suspended.

4.5.7QUIT

This command closes any files that iECM-86 has opened and exits to DOS. Note that this command can be used even if the target is running. iECM-86 sets the selected COM port to 9600 baud, 8 bits, no parity and one stop bit. The port is left in this state by iECM-86 when control is returned to DOS.
