I'm a new allstar user and have been testing a stand alone simplex node for a few weeks now. Kudos to all involved in the development of this great system! My system is in "Simplex Dumb Phone Control mode". From the comments in app_rpt.c the (*) key is supposed to toggle the transmitter and the (#) key is supposed to turn the transmitter off. In fact what I found was that any DTMF key turned the transimtter on and both (*) and (#) toggled it. After realizing this was not likely a configuration issue, believe me I tried MANY combinations, I started perusing the source. Turns out changing line 16607 in app_rpt.c as follows fixes this issue. From: else if (keyed && !*keyed && (c = myrpt->p.funcchar)) To: else if (keyed && !*keyed && (c == myrpt->p.funcchar)) Obviously the intent is to test for equality not assign 'c' a new value. Not sure if this is the right place to report this, if not hopefully someone will point me in the right direction. -- Thanks, Mike KB7XP
