VT100 emulation
« on: 2017.May.18. 23:29:30 »
On the Spanish Retrowiki web page they have thought about implementing a BBS. But Retrowiki is a multi-computer web, not like this one, so they are at the same time thinking a way to easy connect every model. This is easy on Serial port provided computers, or by means of add-ons or hacks, but the hard side of the idea is to implement a form of VT100 emulator on computers never used to do BBS.

I have read here about the VT100/Prestel Rom planed for the EP320, never realised, but also about an "Enterprise BBS" run on Holland connecting the computers to Telephone Modem. ¿What applications where used?, ¿May be CP/M apps?

Now, in Retrowiki they plan to use a PC as the intermediate to the WWW, using cheap USB to RS232 adapters.

BBS was very popular for Amiga and Atari ST owners, but also for C64 and CPC ones.

I have found a page with the most used CPC application, AnsiTerm, with the binary, source and disks included.

It would be a must to be able of some sort of communication with our loved computers....

There is it what I have about it.

All the docs say that the software has been written for the serial/modem card supplied by Bugtronics, but as the source is provided, I will try to use the internal software serial port connected to a PC running a modem emulator.

I feel a little strange reading the conversations through BBS dated in 1988 between Werner Lidnner(Enterprise GMB), Andy Burnham(Datquip Electronics and also Paintbox writer), Søren Rasmussen(software developer) and Finn Stadel Nielsen(Bugtronics).....

They talk about the development of the Serial-Modem card, but also about other technical or private topics.

They even do a good mention about A-Studio....






Edit: There is another very popular Andy Burnham, politician of the Labour Party, actually governor at Manchester.

Zozo, trying to modify the Serial/Net baud rate table on segment 01 implies to fix the EXOS checksum, correct?



The first  word is the bit-rate, and the third byte is the wait-state, they must change accordingly but not less than 1, I think.

The bit-rate has added 243 or 244 as a constant.


So 19200 baud would be more or less 251(00FBh, 01h), and 38400 would be 246(00F6h ,01h).

Midi(31250 baud) is between them, approximately 248(00F8h, 01h).

Some technical instrument must be used to probe this....
