MIRAN Terminal access quit working.

[TDMtek]

We are experiencing a issue with our MIRAN (IRA) card. We had a tech attempt to perform a backup using the "A" drive. He was able to log-on and navigate to the “backup configuration” option page, at that point he inserted a PCMCIA card; It was not a blank card, but it was a card we have used several time before without causing this issue.
So now the issue, when he inserted the card, the laptop screen he was using went blank. Now we are unable to get anything to appear on the screen anytime/every time we try to access the MIRAN card.
The card is still functioning and we can access the TUI to do message changes.

Any thoughts or seen this before?

If it's an Option 11c, are you entering AX (Miran TTY port?). Have you also tried using "~"

All the best

If it's working, then leave it alone!.

Have seen MIRANs which don't work with USB serial port adaptors.

Moving to a built-in serial port on another laptop works fine. It appears that built-in serial uses BIOS calls but USB uses higher level Operating System calls so MIRAN timing may be fussy. The USB adaptor is fine for Call servers, sig servers, etc - only the MIRAN fails.

Other than no serial comms, is the MIRAN working?

Yes the RAN recordings work, and we can access the RAN admin using the telephone access to manage and change the recordings if we were to need to; Just the “terminal” access is inoperative. We never tried setting up the web access when we installed the card, so I haven’t tried to access the web-browser interface using an Ethernet cross-over cable.
The Terminal assess was fine till he placed the CF card into the A-drive slot; then it just quit displaying anything; screen went blank, and doesn’t respond to any input.
At this time we are trying to agree to an off hours’ time to do a card reset, and we will have a spare card at that time just in case we have to replace the card and re-record all the messages.

Haven't seen that before but could be part of the general flakiness of MIRAN serial ports :-(
