Second,is there any way to open an RS-232 channel without clearing all variables, besides using a machine language routine? Thanks in advance, Yattei.

Sorcery. Witchcraft. You'll need eye of newt.... But seriously, folks. Do you remember how the Apple II generated sound? It took an I/O line and manually pulsed it at the desired frequency, courtesy of adelay loop. Now.... imagine trying to do it to two lines simultaneously *AND* keeping the correct frequencies that DTMF tone dialing requires. Can you say "a way to tone dial that is sure to make you pull your hair?" Can you say "stupid?" The real trick is in keeping the correct frequencies. Any moron can do it on one line, but two are harder. Anyways, I seem to recall that I had wrangled some code out of an ex-Anchor employee that did a fair job of tone dialing. Unfortunately, I am sure it is copyrighted. Tear into Autocom or whatever trash they bundled with the modem and dig it out. ] Second,is there any way to open an RS-232 channel without clearing all ] variables, besides using a machine language routine? The variables get cleared because the RS232 buffers are placed at the top of RAM, which happens to be where variables are. You need to relocate these buffers. Then fool OPEN into placing the buffers where you want them. ] Thanks in advance, ] Yattei. ] -- jgreco@csd4.milw.wisc.edu Joe Greco at FidoNet 1:154/200 USnail: 9905 W Montana Ave PunterNet Node 30 or 31 West Allis, WI 53227-3329 "These aren't anybody's opinions."
