I would like to use a terminal on my coco2 running os9-level 1. I can redirect output to the terminal using: LIST <FILE> > /P -or- LIST <FILE> > /T1 but when I type TSMON T1 with or without concurrency, my terminal (actually an Amiga) just beeps. I don't see the login prompt. I am using the four-pin interface which came with the computer. --== Carl Haverl ==-- e-mail: ...!harvard!ulowell!applicon!haverl -or- ...!mit-eddie!applicon!haverl -or- ...!sun!applicon!haverl -or- haverl@applicon.com

If it beeps on a return, perhaps the hardware character configuration is not correct. Usually stripping parity on the transmitting side will fix the problem.

I have just successfully added a terminal to my Level II system; I am using this now. Here's some problems I encountered: o Make sure that you are using a modem cable, not a printer cable o Make sure that the CD line is held high. (This may only be necessary with the RS232 pax) o Make sure that the cable you are using is not just a CoCo-to-modem cable, but a null modem cable (Rx and Tx lines swapped.) Good luck.

Carl - Without getting into an excessive amount of detail, the bit banger port (the one you are using) is all but useless for serial communications under os9. This is because it is not a true serial port, but a software controlled UART emulation being done through a few bits on a parallel port. Also, there is no built-in mechanism to announce the arrival of incoming data... in effect, you must babysit the port (look for the arrival of a start bit), or possibly mangle a cable to allow an arriving character to toggle the carrier detect interrupt. There are work arounds, bu the best bet is get yourself to a Radio Shack and get an RS-232 pak (if you can still find one), They're available anywhere from $10 to $30 these days. -- Pete Lyall (OS9 Users Group VP)| DELPHI: OS9UGVP | Eaton Corp.(818)-706-5693 Compuserve: 76703,4230 (OS9 Sysop) OS9 (home): (805)-985-0632 (24hr./1200 baud) Internet: pete@wlbr.eaton.com UUCP: {ihnp4,scgvax,jplgodo,voder}!wlbr!pete

Greeting- I used the bit banger port on my venerable 64k f board machine for a couple of years under level one with no problems. Just make sure the cables are correct and start tsmon with the proper syntax (tsmon /t1 &), and you should be ok. The only time I had any problems was when one person was working on the console, and another on /t1 and one or the other of them was involved in disk access. This caused all other I/O to be halted due to the design of the disk controller. If you have a controler with some cache memory this will not be a problem. Of course after the disk operation is done, both the console and /t1 have no trouble with I/O. -Brett uucp............!rutgers!cmcl2!esquire!wynkoop voice...........212-266-0741 OS9 seven steps ahead of OS/2
