Following are AT commands for enabling V.23 between the dsPIC03F Soft Modem and
US Robotics Model 5686E Reference Modem. If the AT command is valid,
HyperTerminal displays 'OK' as the response message. If the AT command is invalid or
unsupported, HyperTerminal displays 'ERROR' as the response message.
Supported AT commands for V.23 connection on US Robotics Modem:

Following are AT commands for enabling V.21 between the dsPIC30F Soft Modem and
US Robotics Model 5686E Reference Modem. If the AT command is valid,
HyperTerminal displays 'OK' as the response message. If the AT command is invalid or
unsupported, HyperTerminal displays 'ERROR' as the response message.
