palmheads Posted February 6, 2017 Share Posted February 6, 2017 Hi Been trying too get some serial communication working between my Tandy 102 & TI-99/4a. Have been doing these sorts of projects for years. The null modem cable I use works with my Tandy 102 with: Transferring files to and from Android using a USB OTG cable, a disk emulator called mComm on my Android Nexus 5, USB->Serial converter, null modem cable Transferring files to and from Ubuntu Linux using an app called desklink, USB->Serial converter, null modem cable Am fairly confident my null modem cable is a good one. Got a website detailing some of the stuff interfacing the Tandy with things over the years (seriously needs an update) http://www.planetnz.com/palmheads/tandy.php Idea was too try & transfer a TXT file stored on a DSK file on the CF Card of the nanoPEB to the Tandy 102. First step was too put each machine into Terminal mode to see if I can echo out commands in full/half duplex on both machines. I set up the Tandy to receive in 38N1D, which is 300 baud, send chars using 8 bits data, No error checking parity, 1 pulse at end of each char, disable remote control of data output. Then set the Tandy 102 TELCOM app into Terminal Mode I then tried both the Terminal Emulator II and the Mass-Transfer 4.3 application on the XB 2.7 module. Terminal Emulator II - 300 baud, No parity, tried Full and Half, RS-232 #1 in terminal mode Mass-Transfer 4.3 - 300 baud, RS-232 #1, trying different combos of line feed toggle, echo etc in terminal mode I literally get no response at all at either end. No data is transferred between either. What are the changes the RS-232 on the nanoPEB is faulty? Can anyone see any obvious issue with my settings? Does the TI need a special null modem cable? cheers Daryn 1 Quote Link to comment Share on other sites More sharing options...
+arcadeshopper Posted February 6, 2017 Share Posted February 6, 2017 (edited) neither of those programs support a nanopeb.. Depending on what verson you have you may have a 16550 uart or a 9902.. The only programs that support the nanopeb that I know of are cfhdx1, Stuart's browser, timxt http://atariage.com/forums/topic/259886-timxt-with-nanopeb-version-1/?hl=%2Bterminal and DSR access such as from basic..

Shift838 Posted February 6, 2017 Share Posted February 6, 2017 TE II at 300 baud will also work if the UDS settings are right. Hopefully soon Insane Multitasker will be able to do some final testing with the latest version of TIMXT he was able to get working a couple of months ago. So far all my testing has worked well with it. 2 Quote Link to comment Share on other sites More sharing options...

+arcadeshopper Posted February 6, 2017 Share Posted February 6, 2017 Ok I lied a v1 nanopeb will work in term emu ii. Its 7e1 300 baud.. I used a null modem to my pc rs232.. So to a 102 it's prob straight through no null needed Sent from my LG-H830 using Tapatalk Quote Link to comment Share on other sites More sharing options...
+Lee Stewart Posted February 6, 2017 Share Posted February 6, 2017 I do not know whether this will help, but IIRC, the TI-99/4A RS232 card is configured as DCE (as a modem), whereas I know the nanoPEB serial port is configured as DTE (as most computers) and only supports DTR and CTS handshaking signals. ..lee 3 Quote Link to comment Share on other sites More sharing options...

So far all my testing has worked well with it. If you'd like to upload the test version you are using, feel free to do so. Just call it TIMXTNANO or similar to distinguish it. Either in this post or the one ArcadeShopper references above... I'll try to find time to upload an updated version in a week or two. 2 Quote Link to comment Share on other sites More sharing options...

That will make many users happy. It would probably be better to start a new Topic so it's not buried and probably in the Development forum.. I can link the posting to messages here. what do you think? Edited February 6, 2017 by Shift838 Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted February 6, 2017 Share Posted February 6, 2017 Awesome! Will keep a look out for that then! A thought occurred to me -- does your TI have the F18A video mod installed? TIMXT works only with the F18A and 80 columns. If you need something for a standard TI without F18A, I'll modify one of the Mass Transfer variants this week. It won't be able to achieve any high rates of speed but at least it will be an option. 2 Quote Link to comment Share on other sites More sharing options...

Hi InsaneMultitasker - no, mine is just a normal TI. Be cool too see one of those variants works! Cheers! Daryn Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted February 6, 2017 Share Posted February 6, 2017 Hi InsaneMultitasker - no, mine is just a normal TI. I'll PM you when it is ready to test. My nano arrived recently, but I forgot about the power supply needs. Ping me in a few days if you haven't heard back. Any progress on TIMXT for a 9938/58 system? No progress to report. I don't have sufficient clock cycles to multitask these days... 1 Quote Link to comment Share on other sites More sharing options...
Shift838 Posted February 7, 2017 Share Posted February 7, 2017 (edited) See the below post which has the updated TIMXT for use with the NanoPEB v1 9902 version (Requires F18A). HERE Edited February 7, 2017 by Shift838 Quote Link to comment Share on other sites More sharing options...

I tried again last night with TE II setting 7 bit even parity at 300 baud - still not happy with my null modem cable I use everywhere and another straight through cable I have. I'II try getting the TI connected to my PC, might show issues with my nanoPEB. Quote Link to comment Share on other sites More sharing options...

Interesting - wasn't able to get my PC (ubuntu) using terminal echo at 300 baud using TE II & null modem cable communicating at all. So installed a Terminal Serial Emulator on my android phone. Works great with Tandy. Still nothing with the TI, TE II and Nanopeb. Will see if any updated terminal software for the TI fixes things.

+mizapf Posted February 12, 2017 Share Posted February 12, 2017 What term emu are you using on your PC? I recently learned about picocom and found it quite useful (using it elsewhere, not in the TI context). Quote Link to comment Share on other sites More sharing options...
+InsaneMultitasker Posted February 12, 2017 Share Posted February 12, 2017 Hi InsaneMultitasker - no, mine is just a normal TI. Be cool too see one of those variants works! Cheers! Daryn I modified Mass Transfer (40 columns) to work with the nano. I didn't retrofit it with my high-speed routines, so the best speed is 2400 with dropped characters at 4800. I uploaded it to Heatwave for test purposes. Since I am still waiting for the power cord for my nano, I could only verify the program operates with a standard TI. 1 Quote Link to comment Share on other sites More sharing options...

I recently learned about picocom and found it quite useful (using it elsewhere, not in the TI context). I'II give picocom a go! thats looks good! Was actually just using screen initially, it does a real basic terminal. I used to use getty with red hat/centos, but looked a pain in the butt to get up and running with ubuntu - picocom looks good.

+InsaneMultitasker Posted February 13, 2017 Share Posted February 13, 2017 Nice! Will do some research on how to access heatwave User Hyperterminal or equivalent to telnet to the address/port in my signature. I uploaded the file to Heatwave from my TI system, and have not yet transferred it to a PC for any other posting. Quote Link to comment Share on other sites More sharing options...
palmheads Posted February 16, 2017 Author Share Posted February 16, 2017 Still no go with picocom on ubuntu. Worked great with the Tandy 102. Still nothing from TI, TEII & nanopeb Hopefully get some time with InsaneMultitaskers work this weekend. Am wondering if I'm not supplying enough juice to the Nanopeb to drive the RS232 port? Seems weird I get nothing from it (unless its faulty) Quote Link to comment Share on other sites More sharing options...
+arcadeshopper Posted February 16, 2017 Share Posted February 16, 2017 just curious, what kind of serial port is on the pc? card based or usb? Greg Quote Link to comment Share on other sites More sharing options...
palmheads Posted February 16, 2017 Author Share Posted February 16, 2017 just curious, what kind of serial port is on the pc? card based or usb? Greg Am using a serial -> USB convertor - hmmm may well even be that - I might try & install a serial card on the PC - good thinking!
