My friend has just purchased a generic RS-232C board for his Tandy 1000. He also got a Mitac 1200D modem. After hooking it all up, the modem doesn't seem to want to pick up the phone line. Can anybody help? RS-232 Specs: Address: 3F8-3FF (COM1) Interrupt: IRQ4 (Can a generic PC board work with the 1000? It is a Half-card for XT compatibles.) Modem specs: Bell 103 and 212A Compatible Hayes 'AT' command set Transmit level: -9dBm Sensitivity: -45dBm The TERM READY and HIGH SPEED lights stay on all the time. When commands are given or keys are pressed on the keyboard, the SEND DATA and RECIEVE DATA lights flicker briefly. We are using Procomm V2.4.2 Thanx in advance. ========================================================================= Brian O'Neill University of Lowell CS Dept. boneill@hawk.cs.ulowell.edu

The idea is to check if you can talk to the modem directly. (Mirror and Crosstalk have a mode called "local" that explicitly tells the terminal program to go "on-line" regardless of the carrier or other status lines coming from the modem.) If you succeed in getting your terminal program to let you talk to the modem, you should be able to enter AT-type commands directly, eg. AT should result in OK being sent back, and ATDT5551234 should cause it to dial 5551234 and attempt a connection. You could also try the modem, cable, and board on another (known working) setup. This would tell you if the equipment is at fault. Good luck /-^-\ Thomas M.

You may want to check and make sure you're sending upper case characters. I remember my old Hayes 300 would only take upper case. -Richard -- Richard Dervan - Office of Computing Services Georgia Insitute of Technology, Atlanta Georgia, 30332 uucp: ...!{akgua,allegra,amd,hplabs,ihnp4,seismo,ut-ngp}!gatech!gitpyr!ccoprrd ARPA: ccoprrd@pyr.ocs.gatech.edu
