Striketerm UP9600 freezes with WiModem

[admin]

Don't be surprised if Zmodem is problematic.  Remember that these protocols were all expecting less than 20ms of latency because the connection was a phone line.  This is an internet device.  So, the latency is determined by the ping time.  That varies from setup to setup and can be hundreds of milliseconds in some cases.  I find the most reliable protocols to be Xmodem-CRC, Xmodem-1K, and Ymodem-1K.
