Overall, running at 2400 baud, the modem works excellent with my BBS operation. One problem I noted though is that file transfers wouldn't work right when running Punter or X modem protocol. This was previously reported (https://www.cbmstuff.com/forum/showthread.php?tid=485) by another user. I tested my configuration alternately with CCGMS with same results.
I did find out however - at least with CCGMS - that if I set modem type to U9600 and push the baud rate to 9600, CCGMS will properly send software with another computer. So I then jumped over to my BBS and set the baud rate to 9600 - modem was showing same. Now all the BBS sees is garbage characters and can't communicate with the modem, apparently incompatible with talking to the modem in at this baud rate.
Summary: Normal text communication error-free at 2400 baud. Modem communication flawless as well. File transfers will not operate (hangs on the BBS side).
BBS modem init string is: ate1x1s0=0s10=30v1
Goal: desire to run at 2400 baud rate (for this is a commodore 64!) and effectively do transfers.
I've tried the following settings:
AT&k1 / k2/ k3 / k0
Running latest firmware as of today.
Translation mode is set for NONE.
Caller modems for inbound calls had translation modes set to NONE.
User wifi modems used to call BBS: Both Retro-rewind Wifi and CBMStuff.Com WiModems were used.
No animals were harmed in the testing of this.
There have been many C64 BBS's running WiModems for years now. At higher baud rates (9600 baud and higher) you will need to make sure that hardware handshaking is enabled (AT&K1).
Your problem could very well be that you are trying to use a Telnet system with a non-Telnet system. Typically you want to use RAW mode, which is the default. Some BBS's do use a Telnet connection (typically port 23). In these cases you need to enable Telnet translation (AT*T1) or binary data will not be transferred correctly - including file transfers. Both ends have to match for translation type.
I transfer files between my PC and C64 quite often, using XModem or Punter. Make sure you are using the latest version of CCGMS. There was a bug in the Punter protocol from the original version.
Since this seems to be affecting all WiFi modems you have tried this is likely a BBS problem. What BBS are you using?
