Some things I noticed offhand. Does your modem know (or care) what baud rate your DTC port is using? Is it a modem port? If not, you may have to cheat the modem by wiring a cable that makes the modem "think" it is a modem port with DTC high. Try creating a program that uses the FCONTROL intrinsic to send the string to the port. Or set up the port as a printer, instead an spool the string out. If you're in the mood for play, hook up a dumb terminal to the port and see what character strings come out when you invoke your character string. Set "display functions" on. ---------- From: owner-hp3000-l To: Multiple recipients of list HP3000-L Subject: USING HP3000 TO DIAL MODEM Date: Saturday, September 07, 1996 9:13AM Can anyone help with making my HP3000 dial out a phone number to my pager. The modem is connected to a port on a DTC72. I would like to send at commands to dial my pager. I have tried a file equasion with an echo atdt(phone number) >>*backward reference but I get a FSERR 68 Any suggestions would be appreciated.
