Somewhere in the last couple of days I saw mention of a terminal emulator program for the
TRS-80 Model 1, but I don?t remember what it was or where I saw it. I didn?t think about
it because I was able to get kermit on the TRS-80, but I just pulled it out again and
kermit kinda sucks. It types in all uppercase unless I hold down the shift key, and it?s
got no cursor.
Anyone know of something that?s better?

Chris,
I used OmniTerm in the day and found that pretty good. I've got it on a
disk image here:

The manual is linked under the name.

I looked all up & down your page where you talked about fixing the RS232 card and
never saw any mention of what software to use. Was it there and I just missed it? If not,
you really should link it since google keeps bringing that page up near the top whenever I
search for TRS80 serial/rs232 things. :-)
I'm actually having problems with my RS232 board. Once the BR1941 chip heats up a
little it keeps sending the last character over and over and over. That chip gets super
super hot and when I stuck a heat sink on it, it took a lot longer before it went repeat
crazy. I've got a couple of COM8116 chips on order which I'm hoping will fix it.
I got OmniTerm loaded and it's nice it has a cursor. But it still sends uppercase by
default and I have to hold down shift to get lowercase. I see there's a way to remap
the keyboard in OmniTerm, I guess I will have to play with that.
Thanks!

Well bummer. The new COM8116 chips arrived and that didn't fix the problem. They
don't get quite as hot though! But once the RS232 board has warmed up a bit, it keep
transmitting the last byte sent. Doesn't repeat any incoming bytes. Hope it's not
the TR1602 chip that's bad, looking at eBay they are very expensive.

There are a huge number of pin-compatible UART chips from various
vendors. Just a few are:
AMI S1757, S1883
Fujitsu MB8868A
GI AY-5-1013, AY-5-1013A, AY-3-1014, AY-3-1015
Harris, Intersil HD-6402, RCA CDP6402 (CMOS)
Signetics 2536
SMC COM2017, COM2502, COM2505
TI TMS6011
Western Digital TR1402, TR1602
The main differences between the various UARTs are the maximum speed,
whether they support a 1.5 stop bit setting, and whether they need a
negative power supply. The TRS-80 RS-232-C interface should work with
any of them.

From that list, I've worked with the
HD-6402/CDP6402 the most, but I
think I've seen the General Instruments and SMC
chips on a couple
things.

For TRS-80 model 1 disk system with RS232, I used to use a terminal
program written by Lance Miclus (of Winooski VT).
It was called ST80III, or ST80D. It did an OK job of simple terminal
operations, and file transfers.

Thanks for the great list! I was able to find the AY-5-1013A for $5 shipped on eBay. I
just installed it a while ago and it has fixed the problem with the repeating characters!
This is great, now I can do file transfers over the serial and use the TRS-80 as a
terminal.
